Abstract

The synthesis and structures of silaoxazolinium salts 2 and their application to the catalytic Mukaiyama aldol reaction are described. The reaction of (N-amidomethyl) dimethylchlorosilane (1a) or (N-amidomethyl) bis (trimethylsilyl) chlorosilane (1b) with metal salts of weakly coordinating anions such as Na [TFPB](TFPB= B [3, 5-(CF3) 2C6H3] 4–) and Cs [CB11H12](CB11H12–= carba-closo-dodecaborate) gave the corresponding five- ...
