2,6-Dimethoxyphenylnickel(II) complexes, trans- and trans- (L=PMe3, PMe2Ph and PPh3) have been prepared from and LiR.Reactions of n-butyl-lithium with trans- (L=PMe3 and PMe2Ph) in diethyl ether resulted in the facile lithiation at the methyl carbon in the L ligands, giving trans-2> and trans-2>, respectively, after treatment with SiMe3Cl.The complexes trans-> and trans-2> were obtained from the corresponding PMe3 complexes by analogous reactions in the presence of NNN'N'-tetramethylethylenediamine.Intermolecular tertiary phosphine exchanges have been observed between trans- complexes , as well as between trans- complexes, on heating their benzene solutions or on treatment with carbon monoxide.The possible mechanisms are discussed briefly.
