exo-dehydrogenation of alicyclic amine, (ii) hydrosilylation of resultant enamine, (iii) silylium-induced cis-β-amino elimination to open the ring skeleton, and (iv) hydrosilylation of terminal olefin. The present borane catalysis also works efficiently for the C-Nbondcleavage of acyclic tertiary amines. On the basis of experimental and computational studies, the silicon atom was elucidated to play a pivotal

found to be effective for the direct deaminative coupling of two primaryamines to form secondary amines. The catalyst 1/L1 was highly chemoselective for promoting the coupling of two different primaryamines to afford unsymmetric secondary amines. The analogous coupling of aniline with primaryamines formed aryl-substituted secondary amines. The treatment of aniline-d7 with 4-methoxybenzylamine led to
