Carbonyl halides of the Group VI transition metals. I. Molybdenum tetracarbonyl dichloride and some of its derivatives

Abstract

Molybdenum tetracarbonyl dichloride, Mo(CO)4Cl2, has been prepared and characterized. It is thermally unstable and reactive. Substitution compounds with triphenylphosphine and triphenylarsine have been readily obtained. All these compounds are diamagnetic.
