Synthesis,characterization,and spectroscopic studies of palladium(II)and silver(I)complexes of 4-methoxybenzoylmethylenetriphenylphosphorane and 4-fluorobenzoylmethylenetriphenylphosphorane

摘要

The reactions of 4-methoxybenzoylmethylenetri-phenylphosphorane ylide(MOBPPY),{(Ph)3PCHCOC6H4O Me},and 4-flourobenzoylmethylenetriphenylphosphorane ylide(FBPPY)with[Pd(C6H4CH2NH2-k~2-C-N)ClL](L=Py,3-MePy,4-MePy,or PPh3),in equimolar ratios in CH2Cl2 yield[Pd(C6H4CH2NH2-k~2-C-N)L(Ye)]TfO[(L=PPh3,Ye=MOBPPY;L=PPh3,Ye=FBPPY;L=Py,Ye=MOBPPY;or L=3-MePy,Ye=MOBPPY].The reaction of MOBPPY with AgOTf(OTf=CF3SO3)in molar ratios(2:1)using dry acetone as solvent gives[Ag(MOBPPY)2]OTf.
