摘要
The reaction of compounds [Pt2Me4(mu-SMe2)(2)] and cis-[PtPh2(SMe2)(2)] with ligands 4-(2'-C5H4N)C6H4CHNCH2CH2NMe2 (1a) and 4-(3',5'-C4H3N2)C6H4CHNCH2CH2NMe2 (1b) carried out in acetone at room temperature produced compounds in which the imines act as bidentate [N,N'] ligands. Analogous compounds could be obtained in refluxing methanol when cis-[PtCl2(DMSO)(2)] was used as starting material. The corresponding cyclometallation processes leading to platinum(II) compounds with a tridentate [C, N, N'] ligand took place under different reaction conditions, except for metallation of 1a with cis-[PtPh2(SMe2)(2)], which could not be achieved. All compounds were characterized by usual techniques and [PtMe{4-(3',5'-C4H3N2)C6H3CHNCH2CH2NMe2}] (3bMe) was also characterized crystallographically.
