  A new and attractive coupling partner for the synthesis of α‐substituted vinylphosphonates through Suzuki reactions has been developed. The developed O‐centered electrophiles couple with various organoboron reagents to give α‐substituted vinylphosphonates in moderate to excellent yields. This protocol features broad substrate scope, mild conditions, and high efficiency.

  通过铃木反应合成α-取代的乙烯基膦酸酯的新的，有吸引力的偶联伙伴已被开发出来。发达的以O为中心的亲电试剂与各种有机硼试剂偶合，以中等至极好的收率得到α-取代的乙烯基膦酸酯。该协议具有广泛的基板范围，温和的条件和高效率。

  By reacting dialkyl 1-oxo- or 2-oxoalkylphosphonates with benzhydrylamine followed by reduction with triacetoxyborohydride and acid hydrolysis gave corresponding aminoalkylphosphonic acids with satisfactory yields. The use of benzylamine, α-methylbenzylamine and tritylamine was unsuccessful in the case of dialkyl 1-oxoalkylphosphonates whereas conversion of 2-oxoalkylphosphonates was also achieved

  通过使1-氧代-或2-氧代烷基膦酸二烷基酯与苯甲基胺反应，然后用三乙酰氧基硼氢化物还原并进行酸水解，以令人满意的产率得到相应的氨基烷基膦酸。在1-氧代烷基膦酸二烷基酯的情况下，苄基胺，α-甲基苄基胺和三苯甲基胺的使用是不成功的，而2-氧代烷基膦酸酯的转化率也较低，但仍可实现。

  method for the synthesis of organophosphonates through palladium-catalyzed coupling of α-diazo phosphonates with benzyl or allyl halides has been developed. Trisubstituted alkenylphosphonates bearing versatile functional groups can be easily accessed in good yields and with excellent stereoselectivity through this method. Moreover, with similar strategy α-substituted vinylphosphonates can also be attained

  已经开发了一种通过钯催化的α-重氮膦酸酯与苄基或烯丙基卤化物的偶联来合成有机膦酸酯的有效方法。带有通用官能团的三取代烯基膦酸酯可通过这种方法轻松获得，收率高，立体选择性好。此外，采用相似的策略，也可以通过钯催化的N-甲苯磺酰基hydr和芳基溴的偶联反应获得α-取代的乙烯基膦酸酯。提议将钯卡宾的迁移插入作为该反应的关键步骤。
