N,N′-Bis(perfluoroethyl)thiadiaziridine

Photolysis of CF3CF2NNCF2CF3 with S2Cl2 at 0 °C resulted in the formation of the first thiadiaziridine, CF3CF2[graphic omitted]CF2CF3, in 5% yield.

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

Abstract 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 suifur(IV) compounds decompose rapidly at 25 °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.
