SELECTIVE METHODS FOR THE SYNTHESIS OF POLY(ORGANYLTHIO)- AND POLY(ORGANYLSULPHONYL)-SUBSTITUTED ETHENES FROM POLYCHLOROETHENES

Prilezhaeva, Elena N.,Donzova, Natalia E.,Petukhova, Nina P.,Bogdanov, Valentin S.

, p. 235 - 240 (2007/10/02)

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.
