The stereochemistry of cyclopropanation of norbornenes with diazomethane in the presence of Cu, Pd, and Rh compounds has been studied. Stereoselectivity of the cyclopropanation depends on the nature of the transition metal and does not depend on its valent state or ligand environment. The reaction proceeds predominantly asexo-cycloaddition of the methylene fragment. The greatest amount ofendo-isomer (up to 47 %) is formed in cyclopropanation of norbornadiene andexo-tricyclo[3.2.1.02,4]oct-6-ene in the presence of Cu and Rh compounds.
