The Role of an Alkyl–Phenyl Spacer on the Reactivity of Novel Platinum(II) Complexes with Thiourea Nucleophiles

The presented work, submitted as a paper, deals with the substitution reactions of mononuclear and dinuclear platinum(II) complexes of di-2-pyridylaminodiaquaplatinum(II), (Pt1); di-2-pyridylaminomethylbenzenediaquaplatinum(II), (Pt2); 1,2-bis(di-2-pyridy

ELECTROCHEMICAL ALKYLATION OF 2,2'-DIPYRIDYLAMINE

A method was developed for preparation of alkyl-(2,2'-dipyridyl)amines, consisting of the reaction of alkyl halides with the N anion electrochemically generated from 2,2'-dipyridylamine.The alkylation occurs regiospecifically, and CH2Cl2 can also be used as the methylating agent.Complexes of alkyl-(2,2'-dipyridyl)amines with Pd(2+) and Cu(2+) salts were obtained.

Selective Photooxidation of Sulfides Catalyzed by Bis-cyclometalated IrIII Photosensitizers Bearing 2,2′-Dipyridylamine-Based Ligands

A new family of heteroleptic bis-cyclometalated IrIII complexes with formula [Ir((Formula presented.))2((Formula presented.))]Cl ((Formula presented.) =2-phenylpyridinate and (Formula presented.) =2,2′-dipyridylamine or N-benzylated 2,2′-dipyridylamines, were synthesized, characterized, and successfully used as photosensitizers in the catalytic photooxidation of an array of dialkyl, dibenzyl, alkyl aryl, and diaryl sulfides, as well as sulfur-containing amino acids. Furthermore, the reactions proceeded with optimal chemoselectivity, and atom economy under mild conditions. Experimental observations support a dual mechanism in which singlet oxygen and superoxide are the actual oxidants.

Non-conventional synthesis and photophysical studies of platinum(ii) complexes with methylene bridged 2,2′-dipyridylamine derivatives

Methylene bridged 2,2′-dipyridylamine (dpa) derivatives and their metal complexes possess outstanding properties due to their inherent structural flexibility. Synthesis of such complexes typically involves derivatization of dpa followed by coordination on metals, and may not always be very efficient. In this work, an alternative synthetic approach, involving the derivatization step after-rather than prior to-coordination of dpa on metal center, is proposed and applied to synthesis of a number of platinum(ii) complexes with substituted benzyldi(2-pyridyl)amines. Comparison with the more conventional synthetic route reveals greater efficiency and versatility of the proposed approach. The obtained complexes are not luminescent in solution at room temperature, but display blue phosphorescence emission (ca. 415 nm) with the lifetimes of μs order in glassy matrix at 77 K, with additional green (ca. 485 nm) and relatively long living (τ = 3.7 ms) emission in the case of iodine substituted derivative.

Kinetics and mechanistic study of polynuclear platinum(II) polypyridyl complexes; A paradigm shift in search of new anticancer agents

This paper reports on a mechanistic interaction between mononuclear and polynuclear platinum(II) complexes viz; phenyl-dichlorido-2,2′-dipyridinylaminediaquaplatinum(II) (PtC1); di-2-pyridylaminomethylbenzenediaquaplatinum(II) (PtC2); 1,3,5-tris(2,2′dipyr

Ruthenium and Iridium Dipyridylamine Catalysts for the Efficient Synthesis of γ-Valerolactone by Transfer Hydrogenation of Levulinic Acid

The selective and efficient transfer hydrogenation of levulinic acid into γ-valerolactone was performed with new ruthenium and iridium catalysts bearing dipyridylamine (dpa) ligands. Reactions were performed in the presence of formic acid and triethylamine using catalyst loading as low as 0.05 mol % with a ruthenium complex (turnover number = 1980). Recyclability of a ruthenium catalyst was demonstrated by running 6 consecutive reactions in almost quantitative yields.

The synthesis and application of novel Ni(ii) N-alkyl dipyridylaldiminato complexes as selective ethylene oligomerisation catalysts

A series of N-alkyl 2,2′-dipyridylamine ligands of general formula (2-C5H3NR)2NR′, (a): R = H, R′ = Me; (b): R = H, R′ = benzyl; (c): R = H, R′ = methylcyclohexyl; (d): R = H, R′ = neopentyl; (e): R = Me, R′ = Me) were prepared by a modified method involving base-mediated N-alkylation with the respective alkyl halide. Reaction of the ligands, a-e, with NiCl2(DME) allowed for the isolation of μ-Cl Ni(ii) complexes: [Ni(μ-Cl){a}Cl]2 (1a); [Ni(μ-Cl){b}Cl]2 (1b); [Ni(μ-Cl){c}Cl]2 (1c); [Ni(μ-Cl){d}Cl]2 (1d) and [Ni(μ-Cl){e}Cl]2 (1e). The complexes were characterised by FT-IR spectroscopy, magnetic susceptibility measurements, mass spectrometry, elemental analyses and in the case of 1a, SCD analysis. In the case of complex 1e, an acid-mediated hydrolysis process was identified. The product of hydrolysis, the protonated ligand and a tetrachloronickelate salt (1e-A), was characterised by SCD analysis. Activation of 1a-1e with alkyl aluminium reagents generated highly active catalysts for the oligomerisation of ethylene, with activities of up to 864 kg oligomers molNi-1 h-1 and high selectivity toward the formation of butenes. In general, trans 2-butene was observed as the major isomer, with the exception of 1e. In the case of 1e, the selectivity for 1-butene was 98%, thereby demonstrating the significant effect that the introduction of a low degree of steric pressure in the coordination sphere of the catalyst has on selectivity.

Reactivity of bis(pyridyl)- N -alkylaminato methylpalladium complexes toward ethylene: insights from experiment and theory

A series of novel neutral and cationic methylpalladium complexes bearing N-alkyl-2,2-dipyridylaldiminato ligands were prepared and characterized. In the presence of ethylene, the cationic complexes were active as dimerization catalysts, producing a mixture of 1- and 2-butenes. A Pd-ethyl π-ethylene species was identified as the catalyst resting state by low-temperature spectroscopic and DFT studies, which provided insights into the effect of both steric and electronic factors on the observed reactivity.

OLIGOMERIZATION OF OLEFINS

The invention deals with oligomerization, especially tetramerization of olefins by use of a catalyst system comprising an organometalliccomplex of an element of group 3 to 10 of the Periodic Table of the Elements and a didendate nitogen comprising ligand.

Towards selective ethylene tetramerization

And the magic number is... . A large amount of oligomer-free 1-octene (99.9%) was produced from ethylene by a catalytic system based on chromium during the formation of polyethylene wax [see GC-MS chromatogram; the other three significant peaks are methanol (quenching agent), ethyl acetate (needle-rinsing agent), and toluene (solvent)].
