M. Brunner et al., SYNTHESIS OF ALPHA-ALKINYLENAMINES BY TRIMETHYLSILANOLATE-INDUCED ALPHA-DEPROTONATION OF PROPYNE IMINIUM SALTS, Synlett, (8), 1994, pp. 627-628
Iminium salts bearing an alpha-CH group are efficiently deprotonated w
ith sodium trimethylsilanolate in a non-aqueous reaction medium. In th
is manner, little known alpha-alkinylenamines can be obtained from pro
pyne iminium triflates.
