Heteroorganic betaines 3. * Reactions of betaines containing the +P-C-Si-S- fragment

The [Ph3P+-CMe2-SiMe2-SEt]Br- salt was prepared by the reaction of betaine Ph3P+-CMe2SiMeR-S- (1a: R = Me) with EtBr. Acetylation of betaine 1a or Et3P+-CHMeSiMe2-S- (2a) afforded 2,2,6-trimethyl-1,3-dioxa-2-silacyclohex-5-ene-4-thione Me2SiOC(=S)CH=C(Me)O or the [Et3P+-CHMeSiMe2Cl]Cl- salt depending on the reagent ratio. The reactions of betaines 1a,b (1b: R = Ph) or 2 with compounds (R3Sn)2X (X = O or NMe) can be used for the generation of silanones [RMeSi=O] and silaneimines [RMeSi=NMe] in solutions. The reactivity of betaines Ph3P+-CHR1SiMeR2-S- (R1 = H or Me and R2 = Me or Ph) is determined by the equilibrium between the zwitterionic and ylide Ph3P=CR1SiMeR2SH tautomers that exist in solutions.
