摘要：
A metal-free hydrosilylation of N-sulfonyl ketimines under the FLP catalysis has been realized to give optically active amines in high yields with up to 73% ee. Significantly, a chiral borane-catalyzed asymmet-ric hydrosilylation of vicinal diimines was also achieved, affording the desired cis-1,2-diamines with 12- 70% ee's.(c) 2022 Elsevier Ltd.
