Reactions of the complexes cis-[PtCl2(PPh3)2], [PtCl2(dppp)] (dppp = Ph2P(CH2)3PPh2), [MCl2(dppe)] (dppe = Ph2P(CH2)2PPh2, M = Ni, Pd), [PdCl2(bipy)] (bipy = 2,2′-bipyridine) and [AuCl2(bp)] (bp = cyclometallated 2-benzylpyridine) with p-TolSO2NHC(S)NHPh and Et3N in refluxing methanol gave a series of new thiourea complexes containing the ligand bound as a dianion through the S and the NPh groups.
配合物顺式-[PtCl 2 (PPh 3 ) 2 ]、[PtCl 2 (dppp)] (dppp = Ph 2 P(CH 2 ) 3 PPh 2 )、[MCl 2 (dppe)] (dppe = Ph 2) 的反应P(CH 2 ) 2 PPh 2 , M = Ni, Pd), [PdCl 2 (bipy)] (bipy = 2,2'-bipyridine) 和 [AuCl 2 (bp)] (bp = 环金属化 2-苄基吡啶) p -TolSO 2 NHC(S)NHPh 和 Et 3回流甲醇中的 N 产生一系列新的硫脲复合物,其中含有通过 S 和 NPh 基团作为二价阴离子键合的配体。相关的硫脲类 RSO 2 NHC(S)NHPh (R = Me, Et) 和p -TolSO 2 NHC(S)NHCH 2 CH=CH 2也与顺式-[PtCl 2 (PPh 3 ) 2 ] 反应形成相应的复合物
