摘要

Aminals and α-amino ethers afford N, N-dialkylmethyleneammonium salts by reaction with dichloro (dimethyl)-and trichloro (methyl)-silanes, but whereas chlorotrimethylsilane interacts with α-amino ethers to yield iminium salts, the reaction of the latter silane with aminals does not: in situ Mannich reactions may be carried out using these systems, and in the case of the reactions using chlorotrimethylsilane and aminals the reactions can be ...
