Kinetics and mechanism of chlorine exchange between chloramine-T and secondary amines

Dannan,Crooks,Dittert,Hussain

, p. 652 - 656 (1992)

The kinetics and mechanisms of chlorine transfer from chloramine-T (CAT) to several amines are second order and independent of p-toluenesulfonamide concentration; thus, the reaction does not involve disproportionation of CAT to dichloramine-T. From the profile of pH versus rate, the following mechanisms were proposed: (1) reaction of the ionized species of CAT with the ionized amine (ionic mechanism) and (2) reaction of the un-ionized species of CAT with the un-ionized amine (nonionic mechanism). The second-order, pH- independent rate constants calculated for the ionic and nonionic mechanisms were 1.6 and 5 x 106 M-1 s-1, respectively. Although these two mechanisms are kinetically indistinguishable, the rate constant for the nonionic mechanism is of the same order of magnitude as those calculated for similar chlorination reactions involving nonionizable chloramines, such as N- chlorosuccinimide, N-chloroquinuclidine, and N-chloro-N- methylbenzenesulfonamide. The proposed mechanism for the chlorine exchange involves a molecule of water in a cyclic, six-membered transition state.

STERIC FACTORS IN THE SHORT-RANGE SOLVATION OF SECONDARY AMINES

Tayh, Jamal A.,Scott, Ronald M.

, p. 297 - 305 (1990)

Steric aspects of the short-range solvation of proton transfer complexes between 2,4-dinitrophenol and various secondary amines was studied in benzene-DMSO and benzene-dioxane mixed solvent systems.Diisopropylamine was hindered when compared with diethylamine, and 2,2,6,6-tetramethylpiperidine was hindered when compared with 2,6-dimethylpiperidine in forming the proton transfer complex.The smaller electron-donating solvent dimethylsulfoxide was capable of solvating the more hindered amines, but the the bulkier dioxane could only solvate diethylamine and dimethylpiperidine readily.Tetrahydropyran could solvate tetramethylpiperidine weakly, inferring that it did not solvate in precisely the same fashion as does dioxane.It is concluded that the solvation structure is sufficiently crowded as to be sensitive to small changes in the structures of the participants.

Transient Alkylaminium Radicals in n-Hexane. Condensed-Phase Ion-Molecule Reactions

Werst, D. W.,Trifunac, A. D.

, p. 1268 - 1274 (1991)

Time-resolved fluorescence detected magnetic resonance (FDMR) is used to observe alkylaminium radicals formed in n-hexane solutions by electron pulse radiolysis.The ease of observation of aminium radical FDMR signals increases with increasing alkyl substitution of the amine solutes.The results are discussed in terms of the ion-molecule reactions, such as proton transfer, which compete with electron-transfer processes, i. e., the electron transfer from solute molecules to n-hexane radical cations and geminate recombination.

Effect of an Alumina Phase on the Reductive Amination of 2-Propanol to Monoisopropylamine over Ni/Al2O3

Cho, Jun Hee,An, Sang Hee,Chang, Tae-Sun,Shin, Chae-Ho

, p. 811 - 819 (2016)

Various single-phase aluminum oxides were prepared through the thermal decomposition of bayerite, boehmite, and gibbsite. Ni/γ-Al2O3 and Ni/δ-Al2O3 catalysts exhibited higher monoisopropylamine (MIPA) selectivity than the η-, θ-, and κ-Al2O3 supported Ni catalysts for the reductive amination of 2-propanol (IPA) in the presence of hydrogen and ammonia. FT-IR spectra after pyridine adsorption showed that a high number of Lewis acid sites could be correlated with enhancement in MIPA selectivity. Ni/η-Al2O3 and Ni/γ-Al2O3 catalysts exhibited the highest catalytic activity arising from differences in the metallic surface area. Both catalyst activity and selectivity with regards to reductive amination were strongly affected by the nature of the support.

Oxidative Detoxification of Sulfur-Containing Chemical Warfare Agents by Electrophilic Iodine

Smolkin, Boris,Levi, Noam,Karton-Lifshin, Naama,Yehezkel, Lea,Zafrani, Yossi,Columbus, Ishay

, p. 13949 - 13955 (2018)

Mild oxidation of sulfur-containing chemical warfare agents was performed in organic medium by electrophilic iodine reagents. Kinetic experiments on sulfur mustard (HD) showed rapid (t1/2 1/2 ~ 90 min). Higher donor number solvents, such as THF, DMF, or DMSO, showed slower rates with both iodine and NIS. The oxidation of the nerve agent O-ethyl-S-2-(N,N-diisopropylaminoethyl)methylphosphonothioate (VX) selectively to the nontoxic ethyl methylphosphonic acid product exhibited fast rates (t1/2 = 6 min) using NIS in DMSO solution. In all other solvents tested with VX, rates were slower (t1/2 ~ 30-70 min). Oxidation experiments under the same conditions with chloroethyl ethyl sulfide (HD simulant) and O,S-diethyl methylphosphonothioate (VX simulant) led to much faster reaction rates. These transformations are believed to proceed through electrophilic iodine attack on the sulfur moiety and display solvent dependency based on the agents' structural and chemical properties.

Effect of the Ligand Structure on Chemical Vapor Deposition of WNxCy Thin Films from Tungsten Nitrido Complexes of the Type WN(NR2)3

Koley, Arijit,O'Donohue, Christopher T.,Nolan, Michelle M.,McClain, K. Randall,Bonsu, Richard O.,Korotkov, Roman Y.,Anderson, Tim,McElwee-White, Lisa

, p. 8326 - 8336 (2015)

Tungsten nitrido complexes of the type WN(NR2)3 [NR2 = combinations of NMe2, NEt2, NiPr2, NnPr2, NiBu2, piperidine, and azepane] were synthesized as precursors for aerosol-assisted chemical vapor deposition of WNxCy thin films. The effects of the amido substituents on precursor volatility and decomposition were evaluated experimentally and computationally. Films deposited using WN(NMe2)(NiPr2)2 as a single-source precursor were assessed as diffusion barrier materials for Cu metallized integrated circuits in terms of growth rate, surface roughness, composition, and density. In diffusion barrier tests, Cu (100 nm)/WNxCy (5 nm)/Si samples prepared from WN(NMe2)(NiPr2)2 were annealed for 30 min at 500 °C and successfully blocked Cu penetration according to four-point probe, X-ray diffraction, scanning electron microscopy etch-pit test, and high-resolution transmission electron microscopy measurements.

Reductive amination of 2-propanol to monoisopropylamine over Co/γ-Al2O3 catalysts

Cho, Jun Hee,Park, Jung Hyun,Chang, Tae-Sun,Seo, Gon,Shin, Chae-Ho

, p. 313 - 319 (2012)

Co/γ-Al2O3 catalysts with 4-27 wt% cobalt loadings were prepared by incipient-wetness impregnation and used to catalyze the synthesis of monoisopropylamine by the reductive amination of 2-propanol in the presence of hydrogen and ammonia. The catalysts were characterized by X-ray diffraction, H2-temperature programmed reduction, N 2-sorption, and H2-chemisorption. 23 wt% Co loading resulted in the highest catalytic activity and a long-term stability of up to 100 h on stream. 2-Propanol conversion was related to the exposed metal surface area and the number of exposed cobalt atoms. In the absence of hydrogen, the catalyst was progressively deactivated; its initial activity and selectivity were completely recovered upon re-exposure to hydrogen. The deactivation was due to the formation of metal nitride caused by the strong adsorption of ammonia on the surface of the metal phase. Excess hydrogen hindered the phase transition to metal nitride, preventing deactivation.

Zirconocene-Initiated Intramolecular Hydride Transfer in N -Isoalkyl-Substituted Propargylamines

Ramazanov, Ilfir R.,Kadikova, Rita N.,Saitova, Zukhra R.,Dzhemilev, Usein M.

, p. 1191 - 1194 (2018)

The unusual transformation of N -isoalkyl-substituted propargylamines into alkenylamines under the action of Cp 2 ZrCl 2 and organoaluminum compounds (Me 3 Al, EtAlCl 2) has been observed. The proposed mechanism, involving the N -isoalkyl-substituted propargylamine undergoing zirconocene-initiated intramolecular hydride transfer was supported by B3LYP/6-31G(d)/LanL2DZ calculations.

A Lewis Base Nucleofugality Parameter, NFB, and Its Application in an Analysis of MIDA-Boronate Hydrolysis Kinetics

García-Domínguez, Andrés,Gonzalez, Jorge A.,Leach, Andrew G.,Lloyd-Jones, Guy C.,Nichol, Gary S.,Taylor, Nicholas P.

supporting information, (2022/01/04)

The kinetics of quinuclidine displacement of BH3 from a wide range of Lewis base borane adducts have been measured. Parameterization of these rates has enabled the development of a nucleofugality scale (NFB), shown to quantify and predict the leaving group ability of a range of other Lewis bases. Additivity observed across a number of series R′3-nRnX (X = P, N; R′ = aryl, alkyl) has allowed the formulation of related substituent parameters (nfPB, nfAB), providing a means of calculating NFB values for a range of Lewis bases that extends far beyond those experimentally derived. The utility of the nucleofugality parameter is explored by the correlation of the substituent parameter nfPB with the hydrolyses rates of a series of alkyl and aryl MIDA boronates under neutral conditions. This has allowed the identification of MIDA boronates with heteroatoms proximal to the reacting center, showing unusual kinetic lability or stability to hydrolysis.
