Atom-efficient synthesis of BN-heterocycles from oligoboranes and isonitriles
<i>O</i>-Xylyl isonitrile readily inserts into one of the B-B bonds of simple, unactivated linear peraminotri- and tetraboranes. Subsequent thermal rearrangements yield two different types of CB<sub>2</sub>N heterocycles, a 1-azonium-2,4-diboretane-3-ide and a 1,2,4-azadiboretidine, respectively. When heated with a second isonitrile equivalent, these generate 1,3,2-diazaboroles (C<sub>2</sub>BN<sub>2</sub>) and an unsymmetrical 1,4,2,5-diazadiborinine (C<sub>2</sub>B<sub>2</sub>N<sub>2</sub>).
