A novel and general method for the hydroboration of alkenes, including aryl alkenes, 1,1-disubstituted alkenes, aliphatic alkenes, and bio-derived alkenes, using BX3 as the boration reagent in the presence of iPr2NEt is reported. The reaction was also applied to the synthesis of linear and branched 1,n-diborylalkanes. The reaction is thought to proceed by a frustrated Lewis pair type single-electron-transfer
报道了一种在i Pr 2 NEt存在下使用 BX 3作为硼酸化试剂对烯烃(包括芳基烯烃、1,1-二取代烯烃、脂肪族烯烃和生物衍生烯烃)进行硼氢化的新型通用方法。该反应还用于合成直链和支链 1, n-二硼基烷烃。该反应被认为是通过受挫的路易斯对型单电子转移机制进行的。
