The reactions of [M(PEt3)3] (M = Pt (1), Pd (2), Ni (3)) with 3-chlorothiophene, 2-chlorothiophene, 3-nitrothiophene, 2-nitrothiophene, 2-methoxythiophene, 3-methoxythiophene, 2-acetylthiophene, and 3-acetylthiophene afforded thiaplatinacycles of the type [(Et3P)2M(C,S-C4H3RS)], (for M = Pt, R = Cl (4 and 5), NO2 (6 and 7), MeO (8 and 9), Ac (10 and 11); for M = Pd, R = Cl (12 and 13), NO2 (14), MeO
[M(PEt 3)3 ](M = Pt(1),Pd(2),Ni(3))与3-氯噻吩,2-氯噻吩,3-硝基噻吩,2-硝基噻吩,2-甲氧基噻吩的反应, 3-甲氧基噻吩,2-乙酰基噻吩和3-乙酰基噻吩提供了[(Et 3 P)2 M(C,S- C 4 H 3 RS)]类型的硫氨铂环(对于M = Pt,R = Cl(4和5),NO 2(6和7),MeO(8和9),Ac(10和11)); 对于M = Pd,R = Cl(12和13),NO 2(14),MeO(15和16),Ac(17和18),对于M = Ni,R = Cl(19))。当3和2-氯噻吩进行反应,从氧化加成的C-Cl键的所得的另一种化合物可被分离,与制剂[(ET 3 P)2的Ni(CL)(η 1 -T)](20) 。此外,3与2-硝基噻吩的反应还产生了一种由CH活化反应衍生的化合物[[Et 3 P)2的Ni(H)(η 1 -NO 2 T)
