An in situgenerated cationic Pd(II)/bipyridine-catalyzed nucleophilic addition of arylboronic acids to N-sulfonyl arylaldimines was developed and optimized, and the reaction was proceeded highly efficiently and conveniently in CH3NO2. A series of arylboronic acids and N-sulfonyl arylaldimines were surveyed, and 12 of 13 examples gave 90∼96% yields.

first time, we report the application of [RuCl2(η6-p-cymene)]2 in the arylation of N-activated aldimines with boronic acids and its derivatives to afford chiral amines, which are important intermediates in the syntheses of key bioactive compounds. The behavior of the chiral ligands, the imine substrates, and the organoboronreagents were studied. Very good enantioselectivities were obtained.

α-arylated amines from simple linear N-sulfonyl amines and aryl boroxines utilizing dual palladium catalysis involving amine dehydrogenation. Bromobenzene serves as a hydride acceptor, and the ensuing imineintermediate undergoes a novel umpolung arylation. Given the wide availability of primaryamines, this method can be expected to be useful for the synthesis of structurally complex amines with varied

A Pd(II)/NO2-bpy-catalyzed addition of the arylboronic acids to N-tosylaldimines to yield diarylmethylamines with moderate to excellent yield was developed. The use of bipyridines as the ligands is crucial in this reaction. The asymmetric version of the reaction also showed that a moderate high yield and ee value can be obtained using the pymox ligands.

Asymmetric Arylation of Imines Catalyzed by Heterogeneous Chiral Rhodium Nanoparticles
Asymmetric arylation of aldimines catalyzed by heterogeneous chiral rhodium nanoparticles has been developed. The reaction proceeded in aqueousmedia without significant decomposition of the imines by hydrolysis to afford chiral (diarylmethyl)amines in high yields with outstanding enantioselectivities. This catalyst system exhibited the highest turnover number (700) in heterogeneous catalysts reported
