Ylide Reactions of Benzyldimethylammonium Halides

Sato, Yoshiro,Yagi, Yoko,Koto, Masami

, p. 613 - 617 (2007/10/02)

Deprotonation of benzyldimethylammonium halides (10) with sodium amide or n-butyllithium afforded silylated ylide intermediates 11, which were rearranged into N,N-dimethyl-2-benzylamines (13) accompanied by the formation of Sommelet-Hauser and Stevens rearrangement products (12 and 22).The ylide formation by the cleavage of carbon-silicon bonds also is discussed in the reaction of 10 with sodium amide and lithium aluminum hydride.
