반응 단계
A mixture of ethylcyanoacetate, 1,1-dichloro-3,4-dibromo-4-methylpent-1-ene and calcium carbonate is heated in ethanol (100 parts by volume) at reflux in the presence of calcium chloride (22.2 parts) and copper salt as catalyst. The crude ethyl 1-cyano-3-(2',2'-dichlorovinyl)-2,2-dimethylcyclopropane-1-carboxylate is isolated as described in Example 77. Details are given in the following table:
