NN bond cleavage in diazirines by a cyclic diborane(4) compound

Abstract

Reactions of o-carborane-fused diborane(4) with 3H-diazirines led to the complete cleavage of the NN bond, with one nitrogen atom being incorporated into the B–B bond. The molecular and electronic structures of the resultant borylnitrogen compounds were confirmed through single-crystal X-ray analyses and computational studies. The related reaction mechanism was investigated using DFT calculations.
