Recharging spent BN fuel: {Cr(CO)3} mediates the reduction of borazines by hydride and methyl nucleophiles to generate anionic complexes of dearomatized hexamethylborazine. Subsequent quenching leads to the release of a substituted cyclotriborazane, successfully demonstrating the stepwise reduction of a B[DOUBLE BOND]N bond.
