二氯化四(二甲基亚砜)合钌(II)是一种配位化合物,化学式为RuCl2(DMSO)4,其中,DMSO为二甲基亚砜的英文缩写。它存在顺式和反式两种构型,这两种构型都是已知的,但顺式构型(如右图)更为常见。顺式异构体为黄色固体,在空气中稳定,可溶于一部分有机溶剂。它是潜在的抗癌药物。
结构与制备
[编辑]顺式异构体为DMSO配体连接异构。[1]三个DMSO配体为S-键合,另一个为O-键合,对于两个Cl来说是顺式构型。反式异构体也是黄色的,但四个DMSO配体都是S-键合的。顺式可以通过热反应得到,而反式由顺式通过紫外线照射得到。[2]

这些配合物最初由三氯化钌的DMSO溶液在氢气气氛中加热得到。[3]另一种不使用氢气的方法也得到了文献报道。[2][4]
反应
[编辑]顺式RuCl2(DMSO)4和乙酰丙酮、碳酸氢钠在乙醇中回流反应,经提纯后可以得到黄色的顺式二(乙酰丙酮)二(二甲基亚砜)合钌(II)(cis-Ru(DMSO)2(acac)2)。[5]它和苯胺在常温下甲醇-氯仿(2:1)中反应,配位原子为氧的DMSO配体被取代,得到浅黄色的cis,fac-[RuCl2(DMSO)3(NH2C6H5)];若在甲醇中回流反应,则配位原子为氧和硫的两个DMSO配体被取代,得到深黄色的trans,cis,cis-[RuCl2(DMSO)2(NH2C6H5)2]。[6]
潜在应用
[编辑]RuCl2(DMSO)4最初于20世纪80年代早期被认定为抗癌药。[7]后期进一步的研究[8][9]使得其它含DMSO的钌化合物得到了开发,其中一些进行了早期的临床试验。[10]
