چکیده
Cationic rhodium(I) complexes containing the flexible hemilabile phosphine ligand (3-ethoxypropyl)diphenylphosphine efficiently catalyzed the anti-Markovnikov oxidative amination of styrene in tetrahydrofurane at 80 degrees C to produce (E)-1-styrylpiperidine with turnover frequencies up to 75 h(-1) with excellent enamine selectivity (96%).

A series of cationic square planar rhodium(I) complexes of type [Rh(cod){Ar2P(CH2)nZ}], [Rh(cod){Ar2P(CH2)nZ}2] and [Rh{Ar2P(CH2)nZ}2] containing diverse functionalized phosphine ligands of hemilabile character, Ar2P(CH2)nZ (n = 1, 2, or 3; Z = OMe, OEt, OnBu, NMe2, SMe), have been synthesized and fully characterized by spectroscopic means. The crystal structure of representative compounds has ...
متن کاملBrønsted base-modulated regioselectivity in the aerobic oxidative amination of styrene catalyzed by palladium.
Palladium(II)-catalyzed aerobic oxidative amination of styrene with oxazolidinone proceeds with catalyst-controlled regioselectivity: (CH3CN)2PdCl2 (1) and (Et3N)2PdCl2 (2) catalyze formation of the anti-Markovnikov and Markovnikov enecarbamate products, 3 and 4, respectively. Kinetic studies and deuterium kinetic isotope effects demonstrate that these two reactions possess different rate-limit...
متن کاملDevelopment of catalysts for the hydroamination of olefins*
Studies on the development of palladium, nickel, and rhodium catalysts for the hydroamination of dienes and vinylarenes are described. Enantioselective catalysts based on palladium have been developed for the addition of arylamines to dienes and for Markovnikov addition of arylamines to vinylarenes. In addition, nickel catalysts for the addition of aliphatic amines to dienes have been developed...
متن کاملIron catalysts for selective anti-Markovnikov alkene hydrosilylation using tertiary silanes.
Alkene hydrosilylation, the addition of a silicon hydride (Si-H) across a carbon-carbon double bond, is one of the largest-scale industrial applications of homogeneous catalysis and is used in the commercial production of numerous consumer goods. For decades, precious metals, principally compounds of platinum and rhodium, have been used as catalysts for this reaction class. Despite their widesp...
متن کاملPalladium-assisted multicomponent cyclization of aromatic aldehydes, arylamines and terminal olefins under molecular oxygen: an assembly of 1,4-dihydropyridines.
The palladium-assisted one-pot three-component reactions of aldehydes, amines and olefins proceeded smoothly to give 2,6-unsubstituted 1,4-dihydropyridines (1,4-DHPs) using molecular oxygen as a sole oxidant. It also provides efficient Pd-catalyzed aerobic oxidation access to the anti-Markovnikov oxidative amination products of olefins from primary aromatic amines and alkenes. The method is ato...
