Trifluoromethyl thionitrite

Abstract

Trifluoromethyl thionitrite, CF3SNO, a red gas, has been made by the action of NOCl on Hg(SCF3)2, and also from CF3SH with an alkyl nitrite or NOCl, all at low temperatures. It decomposes quickly at room temperature, but very slowly at –78°, to give the disulphide CF3S·SCF3 and NO.

The i.r. spectrum (4000–400 cm.–1) of the solid at –196°, and the gas at low pressure at room temperature, allows the assignment of 10 of the 15 fundamental vibrations. The u.v. and visible spectrum of the gas (at –116° to –20°) resembles that of NOCl.
