Abstract

Nitrosyl halides of iron and cobalt are prepared by reacting dihalides of iron and cobalt with alkali metal nitrite. Nitrosyl halides of nickel are prepared by reacting nickel dihalide with alkali metal nitrite and nickel or zinc powder. The production of ligand-containing nitrosyl halides of iron, cobalt and nickel is also disclosed. Also disclosed is diolefin dimerization using a nitrosyl halide and elemental manganese, zinc or tin.
