Thionyl Chloride → 1,2,2-Trimethyl-3-(2',2',-dichlorovinyl)-cyclopropane-carboxylic acid chloride

Participants

Reaction Steps

0.60 Part of the above carboxylic acid was agitated with 0.38 part of thionyl chloride at 80° C. for 30 minutes in benzene as a solvent to obtain 1,2,2-trimethyl-3-(2',2',-dichlorovinyl)-cyclopropane-carboxylic acid chloride. The acid chloride was agitated with 0.53 part of 3-phenoxybenzyl alcohol in the presence of pyridine at room temperature in benzene as a solvent to obtain 1.02 parts of 3-phenoxybenzyl-1',2',2'-trimethyl-3'-(2",2"-dichlorovinyl)-cyclopropane-carboxylate. The results of the NMR spectrum (60 MHz ) analysis of the so obtained product were as follows:
