On the Reactions of CF3SF4Cl, (CF3)2SF2, SF4, and OSCl2 with Trimethylsilyl Cyanide

A moderately stable hexacoordinated sulfur(VI) compound with four different kinds of ligands, CF3SF2(CN)2Cl, results when CF3SF4Cl is reacted with (CH3)3SiCN.The latter compound also gives F2S(CN)2 and (CF3)2S(CN)2 with SF4 and (CF3)2SF2, respectively.These tetracoordinated sulfur(IV) compounds decompose rapidly at 25 deg C but are stable at lower temperatures.With OSCl2 and SCl2, the white solids OS(CN)2 and S(CN)2 result.This provides a new, convenient route to S(CN)2. - Keywords: (Trifluoromethyl)chlorodicyanodifluorosulfur(VI), Dicyanodifluorosulfur(IV), Dicyanobis(trifluormethyl)sulfur(IV), Thionyl Cyanide
