The reaction of ethyl diazoacetate (1) with CuCl2 was investigated. Ethyl chloroacetate (2), ethyl dichloroacetate (3) and a mixture of ethyl dichloromaleate (4) and ethyl dichlorofumarate (5) were produced. These products were explained by assuming 1-chloro-1-ehtoxycarbonylmethylcopper complexes, (10) and (11). The reactions of 1 with HgCl2 and CoCl2 were examined in detail as reference reactions from the mechanistic view point.
