摘要

1. Process for the preparation of perhalogenoalkylthioethers, characterized in that an alkali metal thiophenate is reacted with a compound of the formula X1 CF2 X2 in which X1 represents chlorine or bromine and X2 represents chlorine, fluorine, the CF3 radical, the CF2 Cl radical or the CFCl2 radical, but if X1 represents bromine X2 cannot represent chlorine and if X1 represents chlorine X2 cannot represent fluorine or the CF2 Cl radical, in a non-nitrated polar aprotic solvent under a pressure greater than 1 bar.
