Copper-Catalyzed Regiodivergent and Enantioselective Hydrosilylation of Allenes
JOURNAL OF THE AMERICAN CHEMICAL SOCIETY(2022)
摘要
A copper-catalyzed regiodivergent hydrosilylation of a wide range of simple allenes is reported. Linear and branched allylsilanes were formed by judicious choice of solvents. Furthermore, branched allylsilanes were obtained with high enantioselectivity (up to 97% enantiomeric excess) with the aid of a C2-symmetric bisphosphine ligand in the unprecedented asymmetric allene hydrosilylation.
