The reaction of N,N-dialkyl-N-(trimethylsilyl)methyl-γ- (methoxycarbonyl or cyano)allylammonium salts (1e, g, h) with cesium fluoride in N,N-dimethylformamide (DMF) did not form the expected allyl rearrangement products 3 of N-methylides 2, and instead gave N,N-dialkyl-3-(methoxycarbonyl or cyano)-2-(fluoromethyl)propylamines (9e, g, h) as the main product. The reaction mechanism is discussed.

Fluoride-ion induced desilylation of N-benzyl-N-methyl-N-(2-alkenyl)-N-ammonium halides gave N-methylide intermediates which were isomerized to N-methyl-N-(2-alkenyl)-2-methylbenzylamines (Sommelet-Hauser rearrangement products) an
