latter from the previously described bridged benzimidazolones by treatment firstly with phosphoryl chloride followed by thiourea. The bridged benzimidazolethiones formed complexes with mercury, palladium and copper salts but not with iron, cobalt, nickel, zinc, platinum, cadmium, silver or thallium. The imidazolethiones complexed with iron, cobalt, nickel, copper, zinc, tin, cadmium, palladium, platinum
已经制备了一系列N,N′-多亚甲基桥连的咪唑-和苯并咪唑-2-硫酮,该桥含有1至6个亚甲基,前者是通过N,甲基-咪唑被α,ω-二溴代烷烃烷基化然后再进行硫代反应而制得的。首先用磷酰氯处理,然后用硫脲处理。桥联的苯并咪唑硫酮与汞,钯和铜盐形成络合物,但与铁,钴,镍,锌,铂,镉,银或th形成络合物。咪唑硫酮与铁,钴,镍,铜,锌,锡,镉,钯,铂和银盐络合。
