Abstract
Abstract Reactions of the cyclopalladated N , N -dimethylbenzylamine chloro-bridged dimer with 2-benzylpyridine (bpH), 2-benzoylpyridine (bopH), and acetanilide have been studied in acetic acid/chloroform at 50°C. 2-Benzylpyridine readily undergoes ligand exchange to afford the six-membered cyclopalladated complex [PdCl(bp)] 2 in a high yield. In contrast to bpH, 2-benzoylpyridine reacts in two time-resolved steps. A bis-adduct, trans -[PdCl 2 (bopH) 2 ], having no palladium—carbon bond, is formed first, followed by precipitation of the cyclopalladated species. Acetanilide does not react with the N , N -dimethylbenzylamine complex at all. The reasons for such different behaviour of these three ligands are discussed taking into account some of the 1 H NMR spectral data.
