Abstract

Abstract In free-radical reaction of cis-β-phenylvinylcobaloxime with bromotrichloromethane the primary product, phenylacetylene, arises as a result of elimination, and further it adds the bromotrichloromethane. Similarly proceeds the reaction between β-phenylethylcobaloxime with bromotrichloromethane. The values of absolute rate constants and their relation to the nature of the axial ligand completely agree with the assumption that in the reactions in ...
