Reaction Steps

Thus, for example, in Pesticide Science (1974) 5, 791-799 it is shown that the reaction between ethyl diazoacetate and 1,1-dichloro-4-methylpenta-1,3-diene in the presence of copper sulfate to produce ethyl 2,2-dimethyl-3-(2,2-dichlorovinyl)-cyclopropanecarboxylate, results in a product which is contaminated with up to 20% of ethyl fumarate and maleate.
