Studies on transition-metal nitrido and oxo complexes.: Part 20.: Oxoruthenates and oxo-osmates in oxidation catalysis;: cis-[Os(OH)2O4]2- as a catalytic oxidant for primary amines and for alcohols

cis-[Os(OH)(2)O-4](2-) with [Fe(CN)(6)](3-) and other co-oxidants has been studied as a catalytic reagent for the oxidative dehydrogenation of primary aromatic and aliphatic amines to nitriles, the oxidation of primary alcohols to carboxylic acids and of secondary alcohols to ketones. Electronic and Raman spectroscopy have been used to elucidate the nature of the oxoruthenates and oxo-osmates present in a number of reported organic oxidations catalyzed by ruthenium and osmium species.
