Reactivity of Two-Electron-Reduced Boron Formazanate Compounds with Electrophiles: Facile N-H/N-C Bond Homolysis Due to the Formation of Stable Ligand Radicals.

The reactivity of a boron complex with a redox-active formazanate ligand, LBPh2 [L = PhNNC(p-tol)NNPh], was studied. Two-electron reduction of this main-group complex generates the stable, nucleophilic dianion [LBPh2]2-, which reacts with the electrophiles BnBr and H2O to form products that derive from ligand benzylation and protonation, respectively. The… CONTINUE READING
