Reaction Steps

A mixture of 8 g of 3-phenoxy-benzaldehyde and 15.5 g of 1R, trans 2,2-dimethyl-3-(1',2'-dibromo-2',2'-dichloroethyl)-cyclopropane-1-carboxylic acid chloride was warmed to obtain a homogeneous liquid and the mixture was cooled to 20° C. 0.150 g of anhydrous zinc chloride were added thereto and the mixture was stirred at 20° C. for 17 hours to obtain raw RS α-chloro-3-phenoxy-benzyl 1R, trans 2,2-dimethyl-3-(1',2'-dibromo-2',2'-dichloroethyl)-cyclopropane-1-carboxylate whose IR spectrum showed an absorption at 1750 cm-1 (carbonyl) andwhose RMN Spectrum showed the absence of an aldehydic proton.
