摘要：

(Chemical Equation Presented) 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. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
