Abstract

N-Cyanomethyl-, N-ethoxycarbonylmethyl- and N-(3-ethoxycarbonylpropyl)-N-methylbenzylammonium N-methylides 6a,b and 22 have been generated by fluoride ion-induced desilylation of the corresponding N-(trimethylsilylmethyl)benzylammonium salts 5a,b and 21. Sommelet–Hauser 7, 23 and Stevens 8, 24 rearrangement products were obtained from 6a and 22, but not from 6b.
