Enyne Metathesis (Enyne Bond Reorganization)
... is better precedented for platinum than palladium. Trost sagaciously suggested that “further exploration of platinum complexes as metathesis catalysts merits consideration”. The enyne metathesis is dependent on the oxidation state of the metal as Pd(0) instead promotes the Alder-ene reaction (eq 7). ...
