Abstract: Reaction of palladium(II) chloride and potassium tetrechloroplatinate(II) with 5-acylamino and 5-alkylamino-1,2-benzoquinone-2-oximes (qOH; I) has led to complexes of the type M(qo)(2) (2). Pd(qo)(2) was also obtained by the nitrosation of the appropriate phenol in the presence of palladium(II) chloride. The complexes were characterised by elemental analysis, IR and NMR (H-1,Pt-195) spectroscopy. These studies indicated that the ligands are bonded to the metals via the oxime nitrogen and the quinonoid carbonyl oxygen, while mass spectral analysis indicated that the complexes were monomeric. The complexes failed to react with 2,2-dipyridyl, pyridine, and dimethyl acetylenedicarboxylate though the palladium complex, Pd(5-Acqo)(2), reacted with triphenylphosphine to give the corresponding iminophosphoranyl complex.
