New heterocyclic thiophosphoric compounds containing the N-C-N sequence in the ring were prepared by the reaction of thiophosphoryl trichloride (PSCl3) with N,N'-diphenylthiourea. Depending on the reaction conditions, two types of heterocyclic compounds were obtained, namely 2-chloro-1,3-diphenyl-1,3,2λ5-diazaphosphetidine-2,4-dithione (1) and 2-chloro-1,3,5-triphenyl-1,3,5,2λ5-triazaphosphinane-2,4,6-trithione (2). N,N',N″-Triphenylguanidinium chloride (3) was identified in the reaction mixture as a by-product in all cases. The course of reactions was followed by 31P NMR spectroscopy and compound 3 was characterized by single-crystal X-ray diffraction.
通过 thiophosphoryl trichloride (PSCl3) 与 N, N'-二苯基硫脲反应制备了含有环中 N-C-N 序列的新杂环硫代磷化合物。根据反应条件,得到了两种类型的杂环化合物,即 2-氯-1,3-二苯基-1,3,2λ5-二氮杂磷硫杂环-2,4-二硫酮 (1) 和 2-氯-1,3,5-三苯基-1,3,5,2λ5-三氮杂磷杂环-2,4,6-三硫酮 (2)。在所有情况下,反应混合物中检测到了副产物 N, N', N''-三苯基脲盐酸盐 (3)。反应过程通过31P NMR光谱学进行了跟踪,化合物3通过单晶X射线衍射进行了表征。
