Radical Additions of Tertiary Amines to Chlorotrifluoroethylene

Abstract

Radical addition of ethyldimethylamine, cyclohexyldimethylamine, 1-methylpyrrolidine, 1-methylpiperidine, 1-methylperhydroazepine and 1-methylmorpholine to chlorotrifluoroethylene afforded 1 : 1 and 1 : 2 adducts containing 2-chloro-1,1,2-trifluoroethyl groups in the α- or α,α'-positions. Further reaction products were 1 : 2 telomers and secondary products arising by reduction of the chlorine atom in CHFCl groups by tertiary amines. The reaction course and mass and NMR spectra of the products are discussed.
