A neutral 1,4‐diaza‐2,3,5,6‐tetraborinine derivative ( 3 ) featuring a 6π ring system has been synthesized and structurally characterized. The prospective aromatic nature of 3 was assessed by single‐crystal X‐ray analysis, NMR, and UV/Vis absorption spectroscopy as well as computational studies. Furthermore, preliminary reactivity investigations showed that 3 does not only react with diphenyl acetylene but also readily captures CO 2 in a [4+2] cycloaddition under ambient conditions.
