ORGANOMETALLOIDAL DERIVATIVES OF THE TRANSITION METALS X. PHOTOCHEMICAL THERMAL AND SO2 INDUCED 1,2-PHENYL AND 1,2-SULPHINATOPHENYL MIGRATIONS FROM LEAD TO TRANSITION METALS IN THE SYSTEM 5-C5H5)M(CO)nPbPh3> (M = Fe, Cr, Mo, W)

The complexes <(η⁵-C5H5)M(CO)nPbPh3> (M = Fe, Cr, Mo, W) have been studied with respect to their thermal and photochemical stability and their reactivity with respect to SO2.The iron complex is the only complex that exhibits the ability to decompose via a 1,2-phenyl migration to the transition metal under thermal conditions, but photochemically the tungsten complex also exhibits this behaviour.All complexes react readily with SO2 to yield the correponding sulphinatophenyl complexes, LM-SO2-Ph, in high yield.
