Bis‐phosphanated compounds are regarded as the most ubiquitous privileged ligand structures in transition‐metal catalysis. The development of highly atom economical reactions is of great importance for their syntheses because less atom economical methods often require complicated purification procedures under inert atmospheres to remove excess starting materials and byproducts. Herein, the photoinduced
双膦酸酯化的化合物被认为是过渡金属催化中最普遍存在的优先配体结构。原子经济性高的反应的发展对其合成至关重要,因为原子经济性较低的方法通常需要在惰性气氛下进行复杂的纯化程序以去除过量的起始原料和副产物。在此,带有P V(S)-P III的二硫醚单硫化物的光诱导加成反应公开了与烯烃的单键。这些反应仅需相对于烯烃等摩尔量的二硫醚一硫化物即可促进将两种不同类型的含磷基团(例如硫代磷酰基和膦酰基)高度选择性地引入各种烯烃中,而无需任何催化剂,碱或添加剂。
