The present review focuses on recent examples of tetracoordinate boryl groups greatly influencing reactions in organic synthesis. Electron-rich tetracoordinate boryl groups stabilize or activate reactive intermediates such as cations, radicals and π-conjugation systems, and interaction of the intermediates with carbon-boron or heteroatom-boron bonds is the origin of such substituent effects. Unique substituent effects of tetracoordinate boryl groups often promote desired reactions and affect results of reactions such as yield and selectivity of products.
本综述聚焦于四配位硼基在有机合成中对反应产生重大影响的近期实例。富电子的四配位硼基可稳定或活化阳离子、自由基和π共轭体系等反应性中间体，而这些中间体与碳硼键或杂原子硼键的相互作用正是此类取代基效应的根源。四配位硼基独特的取代基效应常常能促进预期反应，并影响反应结果，如产物的产率和选择性。
