Several cyclopropanation catalysts for the synthesis of 3 (2,2-dichlorovinyl)-2,2.dimethylcyclopropanecarboxylates have been studied in this paper.Owing to electron deficiency of 1,1-dichloro-4-methyl-1,3-pentadiene,yield of this reaction is rather low compared with that of 2,5-dimethyl-2,4-pentadiene.Of all catalysts concerned,yield ranged from 25.1% to 47.2%.
