Aryloxazolines, with various substituents on the aromatic ring, have given dimeric cyclo-palladated complexes by reaction with palladium acetate.Steric interaction between ligands causes opening of the molecular structure, as reflected in a long Pd...Pd distance.This structural feature and the fluxionality in solution may be responsible for an unexpected carbonylation reaction which gave diarylketones in good yields.
