SYNTHESIS AND SOME REACTIONS OF 1,1,3,4,4-PENTACHLORO-1,3-BUTADIENE-2-SULFONYL CHLORIDE

Ol'dekop, Yu. A.,Kaberdin, R. V.,Potkin, V. I.

, p. 1459 - 1463 (2007/10/02)

The direct chlorosulfonylation of polychlorodiene systems was realized for the first time for the case of the reaction of 2-H-pentachloro-1,3-butadiene with chlorosulfonic acid.A series of 1-alkyl(aryl)amino-1,3,4,4-tetrachloro-2--1,3-butadienes were synthesized by the reaction of the obtained 1,1,3,4,4-pentachloro-1,3-butadiene-2-sulfonyl chloride with amines.
