highly stereo- and regioselective hydrophosphorylation of terminal alkynes to E-alkenylphosphorus compounds was well developed. It represents a general and practical hydrophosphorylation method, of which diarylphosphine oxide, dialkylphosphine oxide and dialkyl phosphite all had effective P(O)H parts to react with different types of terminal alkynes. Contrary to previous air-sensitive reports, all the reactions
在这里,铜催化的末端炔烃到 E-烯基磷化合物的高度立体和区域选择性氢化磷酸化的协议得到了很好的发展。它代表了一种通用且实用的氢化磷酸化方法,其中二芳基氧化膦、二烷基氧化膦和亚磷酸二烷基酯均具有有效的P(O)H部分与不同类型的末端炔烃反应。与之前对空气敏感的报道相反,所有反应都在空气中进行。由于某些天然产物衍生物和市售除草剂的高立体选择性和区域选择性、良好的官能团耐受性、可扩展性和易于后期衍生化,这种方法非常有吸引力。更重要的是,
