The BN analogue of ortho ‐benzyne, 1,2‐azaborine, is generated by flash vacuum pyrolysis, trapped under cryogenic conditions, and studied by direct spectroscopic techniques. The parent BN aryne spontaneously binds N 2 and CO 2 , thus demonstrating its highly reactive nature. The interaction with N 2 is photochemically reversible. The CO 2 adduct of 1,2‐azaborine is a cyclic carbamate which undergoes photocleavage, thus resulting in overall CO 2 splitting.
