A way to obtain cyclopalladation of unsubstituted 2-phenylimidazole derivatives
摘要:
This work shows the difficulties of obtaining cyclopalladated complexes with 2-phenylimidazole and 2-phenylbenzimidazole as ligands. The protection of the NH group in the heterocycle with an acetyl group allows the formation of several cyclopalladated complexes of both ligands. The X-ray structure of the dimeric acetate-bridge complex of N-acetyl-2-phenyl-benzimidazole is described. The subsequent displacement of the protective group affords a monomeric cyclopalladated complex of 2-phenylbenzimidazole, as well as a coordination complex of this ligand.
