An unusual but efficient method for the synthesis of phosphoroheterocycles, 1,3,2-thiazaphospholidine-4-thione 2-sulfide derivatives, by the reaction of Lawesson's reagent with a variety of u-hydroxy nitriles has been developed. The possible mechanism of the reaction is proposed to involve thiation of hydroxy group in a first step, sequential addition of P-SH to the nitrile and rearrangement resulting
通过劳森试剂与各种 u-羟基腈的反应,开发了一种不寻常但有效的方法,用于合成磷杂环化合物 1,3,2-噻唑膦-4-硫酮 2-硫化物衍生物。提出该反应的可能机制包括在第一步中将羟基硫基化,随后将 P-SH 添加到腈中并重排产生标题的磷杂环。初步生物测定表明,这些杂环化合物具有除草性能。
