Combined KOH/BEt3Catalyst for Selective Deaminative Hydroboration of Aromatic Carboxamides for Construction of Luminophores
The selective catalytic C-N bond cleavage of amides into value-added amine products is a desirable but challenging transformation. Molecules containing iminodibenzyl motifs are prevalent in pharmaceutical molecules and functional materials. Here we established a combined KOH/BEt3 catalyst for deaminative hydroboration of acyl-iminodibenzyl derivatives, including nonheterocyclic carboxamides, to the corresponding amines. This novel transition-metal-free methodology was also applied to the construction of Clomipramine and luminophores.

Direct Synthesis of Diphenylamines from Phenols and Ammonium Formate Catalyzed by Palladium
Arylamines are commercially and synthetically useful compounds with a wide variety of applications. Their preparation has been traditionally achieved using metal-catalyzed C?N coupling reactions with aryl halides. In this work, 17 different diarylamines are prepared from phenols by using ammonium formate as the aminating reagent. Phenolic compounds are more desirable feedstocks, owing to their availability from lignin, making them valuable biorenewable alternatives to aryl halides. Ammonium formate is found to be a convenient surrogate for ammonia and a useful aminating reagent for phenols. Diarylamine products are obtained in good to excellent yields while only water and CO2 are generated as byproducts of the transformation.

Nickel-Catalyzed C-N Cross-Coupling of Ammonia, (Hetero)anilines, and Indoles with Activated (Hetero)aryl Chlorides Enabled by Ligand Design
The Ni(II) precatalyst (C1) featuring the phosphonite ancillary ligand Phen-DalPhos (L1) was employed in the cross-coupling of (hetero)anilines with (hetero)aryl chlorides and in the diarylation of ammonia with (hetero)aryl chlorides to afford heteroatom-dense di(hetero)arylamines. The PAd2-DalPhos precatalyst C4 provided complementary reactivity in cross-couplings of indoles with (hetero)aryl chlorides. Taken together, the demonstration of room-temperature reactivity within each of the reaction classes examined and the observation of useful chemoselectivity at low loading (≤0.5 mol % Ni) and on gram-scale distinguishes C1 and C4 from other metal catalysts (i.e., copper, palladium, nickel, or other) within the field of C-N cross-coupling chemistry.

Hydride-catalyzed selectively reductive cleavage of unactivated tertiary amides using hydrosilane
The first hydride-catalyzed reductive cleavage of various unactivated tertiary amides, including the biologically active aryl-phenazine carboxamides and the challenging non-heterocyclic carbonyl functions, using low-cost hydrosilane as a reducing reagent has been developed. The novel catalyst system exhibits high efficiency and exclusive selectivity, providing the desired amines in useful to excellent yields under mild conditions. Overall, this transition metal-free process may offer a versatile alternative to currently employed expensive reducing reagents, high-pressure hydrogen or metal systems for the selective reductive cleavage of amides.

Palladium-Catalyzed Synthesis of N-Cyclohexyl Anilines from Phenols with Hydrazine or Hydroxylamine via N-N/O Cleavage
Direct access to amines from biomass-based phenols via deoxygenative transformation remains greatly challenging in organic synthesis. Herein, we present a palladium-catalyzed deoxygenative amination of phenols (and their benzyl ether) with hydrazine as nitrogen source. The hydroxylamine/formic acid can be substituted for hydrazine in some cases. This deoxyamination features the involvement of a complex C?O bond and N?N/O bond-cleavage process and allows for the construction of N-substituted cyclohexyl anilines from an array of phenols by finely controlling the reaction conditions in moderate to good yields. (Figure presented.).

KINETICS OF THE REACTION OF THE 2,4,6-TRI-TERT-BUTYLPHENOXYL RADICAL WITH AROMATIC AMINES UNDER QUASIEQUILIBRIUM CONDITIONS, AND THE DISSOCIATION ENERGY OF THE N-H BOND IN AROMATIC AMINES
We have studied the kinetics of the reaction of the 2,4,6-tri-tert butylphenoxyl radical with 11 aromatic amines under quasiequilibrium conditions.The equilibrium constant for each amine was determined from the kinetic results.These values, together with their temperature dependence, were used to calculate the dissociation energy of the N-H bond in the 11 aromatic amines.By using earlier results for the reaction of the aroxyl radical with cumyl hydroperoxide, catalyzed by aromatic amines, we have calculated the rate constants for the reaction of 10 aminyl radicals with cumyl hydroperoxide and of cumylperoxy radicals with 10 aromatic amines.
