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 [PtMe4-(3′,5′-C4H3N2)C6H3CHNCH2CH2NMe2}] (3bMe) was also characterized crystallographically.Key words: platinum
化合物[Pt2Me4(µ-SMe2)2]和顺式-[PtPh2(SMe2)2]与配体4-(2'-C5H4N)C6H4 CHN CH2CH2NMe2 (1a)和4-(3',5'-C4H3N2)的反应)C6H4CHNCH2CH2NMe2 (1b) 在室温下在丙酮中进行生成的化合物,其中亚胺充当二齿 [N,N'] 配体。以顺式-[PtCl2(DMSO)2]为原料,回流甲醇可得到类似化合物。相应的环金属化过程导致具有三齿 [C,N,N'] 配体的铂 (II) 化合物在不同的反应条件下发生,除了 1a 与顺式-[PtPh2(SMe2)2] 的金属化,这不能达到了。所有化合物均采用常规技术表征,[PtMe4-(3',5'-C4H3N2)C6H3CHNCH2CH2NMe2}] (3bMe) 也进行了晶体学表征。 关键词:铂、亚胺、吡啶基、嘧啶基、环金属化、
