ORGANOSILICON AND ORGANOPHOSPHORUS COMPOUNDS WITH PSEUDOHALOGEN GROUPS. 1. SYNTHESIS OF ALKOXYDIMETHYLSILYL CYANIDES AND THEIR REACTIONS WITH METAL FLUORIDES

Article abstract of DOI:10.1007/BF00961242

Alkoxydimethylsilyl cyanides were syntesized by the exchange reaction of the corresponding alkoxydimethylchlorosilanes with trimethylsilyl cyanide, and also by the reaction of the former compounds with HCN in the presence of triethylamine (the latter method were preferential).Reactions of silyl cyanides with SbF3 and ZnF2 were studied.It was found that the reaction of silyl cyanides with SbF3 leads to the formation of Me2SiF2 and the corresponding alkoxydimethylfluorosilanes, which were also obtained by countersynthesis from alkoxydimethylsilylchlorosilanes and metal fluorides (SbF3, ZnF2, CsF).Dimethylfluorosilyl cyanide was obtained by the reaction of silyl cyanides with ZnF2.
