Four-Electron Oxidative Formation of Aryl Diazenes Using a Tantalum Redox-Active Ligand Complex

Four-Electron Oxidative Formation of Aryl Diazenes Using a Tantalum Redox-Active Ligand Complex

The active ingredient: The bis(μ‐imido) tantalum dimer {[ONOred]Ta(μ‐N‐p‐tolyl)(py)}2 releases the aryl diazene (p‐tolyl)NN(p‐tolyl) upon four‐electron oxidation with PhICl2 (see scheme; py=pyridine). Studies suggest that the redox‐active [ONOred]3− ligands act to collect single‐electron oxidation...

description The active ingredient: The bis(μ‐imido) tantalum dimer {[ONOred]Ta(μ‐N‐p‐tolyl)(py)}2 releases the aryl diazene (p‐tolyl)NN(p‐tolyl) upon four‐electron oxidation with PhICl2 (see scheme; py=pyridine). Studies suggest that the redox‐active [ONOred]3− ligands act to collect single‐electron oxidation equivalents for the multielectron reaction.
