feasibility of the addition of CCl4 to linear and cyclic olefins and dienes in the presence of chromium and ruthenium complexes was established. The influence of water as a nucleophilic additive and the influence of the olefin nature, the catalyst central atom, and its ligand environment on the reaction selectivity and product yields were investigated. It was shown that the addition of water to chromium and

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.
