Indenylidene complexes of ruthenium: Optimized synthesis, structure elucidation, and performance as catalysts for Olefin metathesis - Application to the synthesis of the ADE-ring system of nakadomarin A

An optimized and large scale adaptable synthesis of the ruthenium phenylindenylidene complex 3 is described which employs commercially available diphenyl propargyl alcohol 5 as a stable and convenient carbene source. Previous ambiguities as to the actual
