Abstract
The ligand-exchange reaction between {Pd(dmba)C1}2 (dmba = N,N-dimethylbenzylamine) and various oximes such as 3,4-(Me)2C6H3C(CH3)=NOH (1), 4-OMeC6H4C(CH3)=NOH (2), 4-BrC6H4C(CH3) =NOH (3) and α-tetralone oxime (4) was studied. The products obtained were found to be chloro-bridged complexes. The reactions of these complexes were investigated with triphenylphosphine and acetylacetone. The resulting complexes were analysed by IR, 1H NMR and 13C NMR methods. For one of the complexes, [{Pd(4,5-(CH3)2C6H2C(CH 3)=NOH)(C1)}2] (1a), the structure was investigated by single crystal XRD. © 1997 Elsevier Science Ltd.
