Borataalkene Hydrofunctionalization Reactions

The hydrofunctionalization of alkenes is a foundational class of reactions; however, the analogous reactions for BC bond-containing species have been virtually unexplored. This work unearths a range of BC hydrofunctionalization reactions with the 9-borataphenanthrene anion, including hydroalkylation, hydroarylation, hydroalkynylation, hydroamination, hydroalkoxylation, and hydration. The unique reactivity represents an addition to the synthetic chemist’s toolbox to access functionalized tetracoordinate borates.烯烃的氢官能化反应（hydrofunctionalization）是一类基础反应；然而，针对含B=C键物种的同类反应却几乎尚未被探索。本研究首次发掘出一系列以9-硼杂菲阴离子（9-borataphenanthrene anion）为反应底物的硼碳双键氢官能化反应，涵盖氢烷基化、氢芳基化、氢炔基化、氢胺化、氢烷氧基化及水合反应。该独特的反应活性为合成化学家的工具库增添了全新的合成手段，可用于制备功能化的四配位硼酸盐（tetracoordinate borates）。
