Reaction of 2-pyrrole carboxylates with Lawesson's reagent at elevated temperatures results in the corresponding thionoesters, concurrent with the production of a new class of pyrrole annulated with the (1,3,2)-thiazaphospholidine unit. X-ray crystallography was used to identify the pyrrolic thiazaphospholidine, which was found to have unique structural features compared to literature analogues. Addition
2-吡咯羧酸盐与Lawesson试剂在升高的温度下反应生成相应的硫代磺酸酯,同时生产出一类新的与(1,3,2)-噻唑膦环化的吡咯。X射线晶体学用于鉴定吡咯并噻唑烷膦,与文献类似物相比,吡唑并膦具有独特的结构特征。发现将BF 3 ·OEt 2添加到硫磺化程序中可生成相应的F-BODIPY,在一个反应釜中构成一个四步反应。本文讨论了涉及混杂Lawesson试剂的这些反应的范围和局限性。
