Simple copper/TEMPO catalyzed aerobic dehydrogenation of benzylic amines and anilines.
CuBr(2) with 2,2,6,6-tetramethylpiperidyl-1-oxy (TEMPO) has been successfully employed for the aerobic oxidation of primary and secondary benzyl amines in aqueous acetonitrile. Such catalytic systems have previously been used extensively in alcohol oxidation reactions. The same catalyst system was also used for oxidative cross-couplings of benzylamines with anilines. The electronic and steric p...
متن کاملArylation of Benzylic Amines Using Arylboronates
A Ru-catalyzed direct arylation of benzylic sp carbons of acyclic amines with arylboronates is reported. This highly regioselective and efficient transformation can be performed with various combinations of N-(2-pyridyl) substituted benzylamines and arylboronates. Substitution of the pyridine directing group in the 3-position proved to be crucial in order to achieve high arylation yields. Furth...
متن کاملDehydrogenation of cyclic amines by a coordinatively unsaturated Cp*Ir(iii) phosphoramidate complex.
The reaction of a Cp*Ir(iii) phosphoramidate complex with secondary amines gives amine, imine-bound Cp*Ir(iii) hydride complexes resulting from amine dehydrogenation. These well-characterized species could serve as models of relevant intermediates that have been proposed in catalytic amine dehydrogenation using related N,O-chelated Cp*Ir(iii) pyridonate complexes.
متن کاملChemoselective Silylative Reduction of Conjugated Nitriles under Metal-Free Catalytic Conditions: β-Silyl Amines and Enamines.
The B(C6F5)3-catalyzed silylative reduction of conjugated nitriles has been developed to afford synthetically valuable β-silyl amines. The reaction is chemoselective and proceeds under mild conditions. Mechanistic elucidation indicates that it proceeds by rapid double hydrosilylation of the conjugated nitrile to an enamine intermediate which is subsequently reduced to the β-silyl amine, thus fo...
متن کاملAn electron poor iridium pincer complex for catalytic alkane dehydrogenation.
A novel electron deficient 4,6-bis(trifluoromethyl)-1,3-phenylene diphosphinite ligand 4 was developed and synthesized. Reaction of Ir precursors with ligand 4 gave chloro(hydride) pincer complex 5, which demonstrated a higher TON in alkane dehydrogenation reactions compared to similar phosphinite based pre-catalysts. The formation of cyclooctene (COE) and tert-butylethylene adducts of the 14e ...
