3-dialkyl-2-(tert-butyldiphenylsilylmethyl)azetidines rearrange smoothly into the corresponding 2-alkenyl-3-(tert-butyldiphenylsilyl)amines upon exposure to BF3·OEt2 in CH2Cl2. The reaction involves sequential σC–N bond cleavage, 1,2-migration of the N-tosyl-aminomethyl group, and deprotonation of the resultant tert-carbenium ions. For the instance in which the carbeniumion formed from migration of the N-tosyl-aminomethyl
