TLDR
The trans-dioxo ruthenium (VI) complex catalyzes the oxidation of secondary alcohols to ketones by N-methylmorpholine-Noxide (NMO) as mentioned in this paper.Abstract:
Thetrans-dioxo ruthenium (VI) complex, [P(C6H5)3C6H5CH2]+[Ru(O)2OAcCl2] or tetrapropylammonium perruthenate catalyzes the oxidation of secondary alcohols to ketones byN-methylmorpholine-N-oxide (NMO). Kinetic studies showed the formation of a complex between catalyst and substrate (alcohol) as the first step in the mechanism.read more

Oxidation of primary alcohols to aldehydes with oxygen catalysed by tetra-n-propylammonium perruthenate
TL;DR: In this paper, a series of saturated and unsaturated non-allylic alcohols to aldehydes with oxygen or air catalysed by tetra-n-propylammonium perruthenate (TPAP), represented as [(n-Pr)4N]RuO4) at 80-110°C is shown to proceed with selectivities of 72-91% at 55-80% alcohol conversion.

The Chemistry of Ruthenium Oxidation Complexes
TL;DR: In this article, the basic preparation, physical and chemical properties of Ru-based oxidation catalysts are discussed, and the catalytic oxidations which they accomplish are given in the succeeding four chapters.

Oxidation of Alcohols, Carbohydrates and Diols
TL;DR: In this article, the authors discuss the most important classes of oxidation effected by Ru complexes, particularly by RuO4, [RuO4]−, RuCl2(PPh3)3, though in fact most Ru oxidants effect these transformations.

TL;DR: The most likely explanation of the concave upward Hammett plots is the involvement of free radical-like transition states that could be formed by the decomposition of organometallic intermediates as discussed by the authors.
