arylation and alkenylation of the alpha-bromoalkenyl phosphonates were investigated with organoboranes and -borates. Arylation was successful with the aryl boronicacids and a palladium catalyst, while alkenylation was found to proceed with alkenyl borates and a nickel catalyst. In addition, an intramolecular Diels-Alder reaction of the diene prepared by the alkenylation afforded the corresponding adduct

modern chemistry. Herein, we use an inorganic phosphorous-containing species, NaH2PO2, to serve as the source of phosphorous that participates directly in the nickel-catalyzed selective alkyne hydrophosphonylation reaction. The transformation was achieved in a multicomponent fashion and at room temperature, and most importantly, the H-phosphinate product generated is an advanced intermediate which can
传统的亚膦酸酯合成方法使用三氯化磷 (PCl 3 ) 作为磷源,导致过程污染严重且能源密集。寻找一种既温和又环保的替代方法是现代化学中一项具有挑战性但回报丰厚的任务。在此,我们使用无机含磷物质 NaH 2 PO 2作为磷源,直接参与镍催化的选择性炔烃氢膦酰化反应。这种转变是在室温下以多组分方式实现的,最重要的是,H- 生成的次膦酸盐产品是一种高级中间体,可以很容易地转化为多种次膦酸盐衍生物,包括带有新 P-C、P-S、P-N、P-Se 和 P-O 键的衍生物,从而提供一种补充方法经典的次膦酸酯合成技术。
