摘要
The synthesis and characterization of the cyclopalladated p-azoxyanisole chloro-bridged dimer [Pd(Azoxy)Cl]2, 1, is reported and its reactions with some salicylideneaniline derivatives (HL1-5) are described. H-1 NMR spectral observations indicate that except for [Pd(Azoxy)(L4)] the mononuclear [Pd(Azoxy)(L)] products are ca 5:1 mixtures of N-trans and N-cis isomers. In the HL4 case (HL4 = salicylidene(2,4-dimethyl)aniline) the only product which was detected is the N-trans isomer. The crystal structure of trans-[Pd(Azoxy)(L1)] (HL1 = salicylideneaniline) (3-trans) is monoclinic.
