Structural study of (oxodimethylenemethane)palladium and -platinum complexes

Structures of (oxodimethylenemethane)palladium and -platinum complexes in solution and in crystalline states were investigated by 1H NMR, IR, and X-ray crystallographical analyses. The following features are disclosed: the structures consisted of contributions from π-allylic and metallacyclobutanone canonical forms; the palladium complex has a larger contribution of π-allylic character than the platinum complex in both states; the degree of contribution of π-allylic character increased upon the increment of solvent polarity and the addition of protic solvent.

A Novel Synthesis of (Oxodimethylenemethane)-palladium and -platinum Complexes

Treatment of ?-allyl-palladium and -platinum complexes bearing a methoxymethoxy group at the 2-position with base give the corresponding oxodimethylenemethane complexes, in contrast to the formation of 2-hydroxy-substituted ?-allyl complexes via acidic hydrolysis.
