with triethylamine base, followed by addition of NaBPh4 gives the salts [PtSC(NR1R2)NR3}(PPh3)2]BPh4 in high yield; a range of thiourea substituents, including chiral, fluorescent and chromophoric groups can be incorporated. The azo dye-derived complex [PtSC(N(CH2CH2)2O)NC6H4NNC6H4NMe2}(PPh3)2]BPh4 has been characterised by a single-crystal X-ray diffraction study. The formation of a fluorescein-derivatised
摘要顺式-[PtCl2(PPh3)2]与三取代硫脲[R1R2NC(S)NHR3]在回流的甲醇中与三乙胺碱反应,然后添加NaBPh4得到盐[Pt SC(NR1R2)NR3}( PPh3)2] BPh4高产;可以引入许多硫脲取代基,包括手性,荧光和发色基团。偶氮染料衍生的配合物[Pt SC(N(CH2CH2)2O)NC6H4NNC6H4NMe2}(PPh3)2] BPh4的特征在于单晶X射线衍射研究。还描述了荧光素衍生的铂-硫脲复合物的形成。顺式[[PtCl2(PPh3)2]与PhNHC(S)NHPh或EtNHC(S)NHEt,三乙胺和NaBPh4的反应分别得到[Pt SC(NHPh)NPh}(PPh3)2] +和已知的阳离子[Pt SC(= NHEt)NEt}(PPh3)2] +,以四苯基硼酸盐的形式分离。顺式-[PtCl2(PPh3)2]与过量的Na [MeNHC(S)N
