Novel class of diboron reagent – boronyl borinic ester – was developed that were generated as B2pin2/secBuLi/TFAA adducts. Detailed NMR with solid-state 2D NMR techniques and ESI-MS investigations were used to get structural insights of these new reagents. The new boronyl borinic esters were proved to be promising for allylic borylations of base-sensitive substrates.
开发了新型二硼试剂——硼酰基硼酸酯——生成为 B 2 pin 2 / sec BuLi/TFAA 加合物。详细的核磁共振与固态二维核磁共振技术和 ESI-MS 研究被用于获得这些新试剂的结构洞察力。新的硼酰基硼酸酯被证明有望用于碱敏感底物的烯丙基硼化。
