Thermolysis of 9‐azido‐9‐borafluorene in heptane solution produces the tetramer of a BN‐phenanthryne. The isolation of the self‐trapping product provides evidence for the involvement of the BN‐aryne in the thermolysis reaction. Its formation may be rationalized by denitrogenation of the azide and ring enlargement.
