hione. This thione undergoes reaction with 1,2-dibromoethane to yield a thiazole bromide salt. Upon heating the thione in diphenyl ether with 2-chloro-1,10-phenanthroline, the hydrochloride salt of 2,2′-thiobis-1,10-phenanthroline precipitated and could be converted into the corresponding free base on treatment with aqueous base. Heteroaryl substituted sulfides could be prepared by treatment of 2-chloro-1
用DMF中的NaSH水合物,DMF中的Na 2 S九水合物或硫脲在回流的乙醇中处理2-氯-1,10-菲咯啉,可轻松获得1,10-菲咯啉-2(1 H)-硫酮。该硫酮与1,2-二溴乙烷反应,生成噻唑溴化物盐。用2-氯-1,10-菲咯啉加热二苯醚中的硫酮后,2,2'-硫代双-1,10-菲咯啉的盐酸盐沉淀出来,经碱水溶液处理可转化为相应的游离碱。杂芳基取代的硫化物可通过在DMF中用吡啶-2-硫酮处理2-氯-1,10-菲咯啉或用碳酸钾处理嘧啶-1-硫酮来制备。
