(Hetero)arene-fused boroles are a class of compounds containing a 5-membered boron diene-ring. Based on their molecular framework, the (hetero)arene-fused boroles can be considered as boron-doped polycyclic antiaromatic hydrocarbons and are thus of great interest. Due to the vacant p orbital on the 3-coordinate boron atom, the antiaromaticity and strain of the 5-membered borole ring, (hetero)arene-fused boroles possess strong electron accepting abilities and Lewis acidity. By functionalization, they can be tuned to optimize different properties for specific applications. Herein, we summarize synthetic methodologies, different strategies for their functionalization, and applications of (hetero)arene-fused boroles.
（杂）芳烃稠合硼咯是一类含有五元硼二烯环的化合物。基于其分子骨架，（杂）芳烃稠合硼咯可被视为硼掺杂的多环反芳香烃，因此备受关注。由于三配位硼原子上的空p轨道、五元硼咯环的反芳香性和张力，（杂）芳烃稠合硼咯具有很强的电子接受能力和路易斯酸性。通过官能团化，可以对它们进行调控，以优化其用于特定应用的不同性能。在此，我们总结了（杂）芳烃稠合硼咯的合成方法、官能团化的不同策略及其应用。
