Alkylvanadium and Alkylniobium Reagents, II. — Niobium‐Induced Reductive Carbonyl Dimerisation NbCl 5 reacts with one equivalent of methyllithium or metallic potassium to give a reagent for the transformation of aldehydes, ketones, benzalchloride, and benzotrichloride to symmetrically substituted ethene derivatives (Tab. 1). The reagent NbCl 5 /K ( 2 ) is distinctly more reactive than NbCl 5 /MeLi ( 1 ). For the reductive carbonyl dimerisation with niobium reagents a mechanism is proposed.
