Previously, It has been reported that the reaction of L.R. with Di and Tri alkyl phosphites afforded the thioproducts. Here in, we have reacted Lawesson’s reagent (L.R.,1) with triethylphosphite 2 in refluxing acetonitrile to give three phosphonate derivatives 3, 4 and 5 respectively. Structures of the later products were confirmed by analytical and spectroscopic evidences.
以前,已经报道了LR与亚磷酸二烷基酯和亚磷酸三烷基酯的反应提供了硫产物。在此,我们使Lawesson试剂(LR,1)与亚磷酸三乙酯2在回流的乙腈中反应,分别得到三种膦酸酯衍生物3、4和5。后期产品的结构已通过分析和光谱学证据得到证实。
