Atom Economical Coupling Of Benzophenone And N-Heterocyclic Aromatics With Smi2

The use of stoechiometric SmI(2)in combination with benzophenone and N-heterocyclic aromatics such as bipyridine, phenanthroline and pyridine allows the directortho-coupling of both partners in an atom economical reaction free of any other coupling additives. The transformation was investigated by(1)H NMR, X-ray studies and theoretical calculations providing reaction intermediates and the reaction mechanism.
