Ba. Gostevskii et al., SYNTHESIS AND UNUSUAL REARRANGEMENT OF SILA-DELTA(2)-DIHYDRO-1,3,4-LAMBDA(4)-OXADIAZINIUM CHLORIDES, Mendeleev communications (Print), (4), 1998, pp. 157-158
The reactions of O-TMS derivatives of 1,1-dimethylhydrazides of triflu
oroacetic and benzoic acids with Me2Si(CHCl2)Cl give 2-organyl-4,4,6,6
-tetramethyl-5-chloro-6 lambda(5)-sila-Delta(2)-dihydro-1,3,4 lambda(4
)-oxadiazinium chlorides which in CDCl3 solution exhibit unexpected de
composition with the formation of Me2SiCl2, DMF and the corresponding
organylcyanide.
