Several new Ni (7a−i), Pd (8a−j), and Pt (9a−j) dithiolenes belonging to the general class [M(R,R‘timdt)2] (R,R‘timdt = monoanion of di-substituted imidazolidine-2,4,5-trithione) have been synthesized by sulfuring the disubstituted imidazolidine-2-thione-4,5-diones (4) with Lawesson's reagent (5) in the presence of the appropriate metal either as powder or as chloride. The obtained compounds have been
几种新的 Ni (7a−i)、Pd (8a−j) 和 Pt (9a−j) 二硫烯属于一般类 [M(R,R'timdt)2] (R,R'timdt = di 的单阴离子-取代的咪唑烷-2,4,5-三硫酮)是通过在适当的金属粉末或粉末的存在下用劳森试剂(5)硫化二取代的咪唑烷-2-硫酮-4,5-二酮(4)合成的作为氯化物。所得化合物已通过 UV-vis-NIR、FT-IR 和 FT-Raman 光谱、CP-MAS 13C NMR 和循环伏安法进行表征,而 [Ni(Me,Pritimdt)2] (7c) 的特征还在于单晶的 X 射线衍射。从复合反式双[O-乙基(4-甲氧基苯基)膦酰二硫代]Ni(II) (10a)和4,5,6,7-四硫基[1,2-b:3,4]的反应混合物中分离-b']diimidazolyl-1,10-diphenyl-3,8-diethyl-2, 作为副产物的 9-二硫酮 (6a)
