General description

Ethyl diazoacetate solution is a diazo compound that is used as a reagent for the cyclopropanation of unsaturated compounds. It is used to prepare cyclopropane and cyclopropane carboxylic acid derivatives by catalytic decomposition of ethyl diazoacetate in the presence of alkenes. It is also a useful reagent for the homologation of cyclic and acyclic ketones without the formation of epoxides as byproducts.
