retroaddition strategy for the generation of phosphinidenes involves thermal and photochemical decomposition of 1-arylphosphiranes and photolysis of 1-aryl-3-phospholenes. Evidence that free phosphinidenes are produced as reactive intermediates includes a lack of dependence of the conversion rate on precursor and substrate concentrations and the nature of the reaction products. These are best rationalized by the
生成膦的逆加成策略涉及 1-芳基膦的热和光化学分解以及 1-芳基-3-膦的光解。游离膦作为反应性中间体产生的证据包括转化率不依赖于前体和底物浓度以及反应产物的性质。通过将膦加成到碳 - 碳 π 键形成三元环和膦二聚化为二膦来最好地解释这些
