Direct Synthesis and Reactions of Bromo(pentafluorophenyl)silanes

Abstract

It is here seen that chloro(chloroformy1)sulfane reacts only monofunctionally. Attempts to replace also the CI atom of the chloroformyl group by the trifluoromethyl group failed. This accords with findings by Zumnch and KiihIersJ in which ClCOSCl was attacked by thiols only at the S-bonded CI atom. Compounds ( I ) and (2) are water-clear, mobile liquids which are stable in absence of moisture (see Table).
