Solvolytically DMSO-promoted reactions of 1,1,1-trifluoroethyl chloride (HCFC-133a) or fluoride (HFC-134a) with nucleophiles
Fluorinated gases HCFC-133a (CF3CH2Cl, bp=6°C) and HFC-134a (CF3CH2F, bp=-27°C) are found highly soluble in DMSO. In their DMSO solutions, oxygen-, nitrogen- and sulfur-nucleophilic reactions may occur in normal

SELECTIVE METHODS FOR THE SYNTHESIS OF POLY(ORGANYLTHIO)- AND POLY(ORGANYLSULPHONYL)-SUBSTITUTED ETHENES FROM POLYCHLOROETHENES
A simple general method for the total substitution of chlorines in polychloroethenes by organylthio groups and its modifications allowing to stop the substitution selectively at a given number of chlorine atoms are reported.Trifluoroperacetic acid (in dichloromethane) is proposed as the oxidant of choice for obtaining the hitherto unknown sulphonylethenes with four and three sulphonyl groups from the corresponding poly(organylthio)ethenes.
