Organosilicon and organophosphorus compounds with pseudohalide groups. 2. Reactions of alkoxydimethylsilyl cyanides with chlorides of tricoordinated phosphorus

Reactions of alkoxydimethylsilyl cyanides with some chlorides of tricoordinated phosphorus (phosphorous chlorides) have been studied. It is shown that, depending on the nature of the phosphorous chloride, the chlorine atoms can either be substituted only for cyano groups, or for alkoxy and cyano groups simultaneously. The results obtained in this work clearly show that alkoxydimethylsilyl cyanides are more reactive reagents for attaching cyano groups to a phosphorus atom than trimethylsilyl cyanide.For Part 1, see 1].For a preliminary communication, see 2].Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 12, pp. 2847–2849, December, 1991.
