Abstract
Abstract The chloro(ligand- C , N )triphenylphosphinepalladium(II) complexes with cyclopalladated N , N -dialkylbenzylamines (alkyl = methyl, ethyl and n-propyl), azobenzene, 8-methylquinoline, dimethylaminomethylferrocene and 2-benzylpyridine undergo lithium chloride-induced solvolysis in acetic acid solvent usually at 80°C to afford the corresponding non-palladated ligands and the poorly soluble, dinuclear complex [PdCl 2 (PPh 3 )] 2 . The reactivity pattern for N , N -diethylbenzylamine derivative II provides evidence that the reaction proceeds in two steps. The first step is palladium—nitrogen bond cleavage to afford the dechelated, σ-bonded zwitterionic complex cis -[PdCl 2 (C 6 H 4 CH 2 NHEt 2 )(PPh 3 )], and the second step is protonolysis of the palladium—carbon bond by acetic acid to yield the final products.
