Efficient and Selective Aerobic Oxidation of Alcohols into Aldehydes and Ketones Using Ruthenium/TEMPO as the Catalytic System
Arné Dijksman,Arturo Marino-González,Antoni Mairata i Payeras,and Isabel W. C. E. Arends,Roger A. Sheldon +4 more
TL;DR: The combination of RuCl2(PPh3)3 and TEMPO affords an efficient catalytic system for the aerobic oxidation of a variety of primary and secondary alcohols, giving the corresponding aldehydes and ketones, in >99% selectivity in all cases.

Efficient ruthenium–TEMPO-catalysed aerobic oxidation of aliphatic alcohols into aldehydes and ketones
TL;DR: The combination of RuCl2(PPh3)3 and TEMPO as discussed by the authors affords an efficient catalytic system for the aerobic oxidation of a broad range of primary and secondary (aliphatic) alcohols at 100 °C, giving the corresponding aldehydes and ketones, respectively, in >99% selectivity.

Mechanism of N,N,N-Amide Ruthenium(II) Hydride Mediated Acceptorless Alcohol Dehydrogenation: Inner-Sphere β-H Elimination versus Outer-Sphere Bifunctional Metal–Ligand Cooperativity
TL;DR: In this article, the authors investigated the catalytic mechanism of a single precatalyst for acceptorless alcohol dehydrogenation (AAD) using a series of kinetic and isotopic labeling studies, isolation of intermediates, and evaluation of Ru(b4Rpi)(PPh3)2Cl (R = H, Me, Cl, OMe, OH) complexes.

Mechanism of Hydride Abstraction by Cyclopentadienone-Ligated Carbonylmetal Complexes (M = Ru, Fe)
TL;DR: In this paper, the hydride transfer process is used as an example of a coordinatively directed abstraction by adding quantitative understanding to some features of this mechanism that are not well understood, and an oxidant as weak as acetone can be used to reoxidize the intermediate ruthenium hydrides without catalyst re-oxidation becoming rate limiting.

Catalytic Oxidations in the Manufacture of Fine Chemicals
TL;DR: In this article, various types of oxidation processes are outlined on the basis of type of catalyst, primary oxidant, mechanism and functional group transformation, since fine chemicals are often relatively complex, multifunctional molecules the chemo- regio and stereoselectivity of such processes are emphasized.

The mechanism of olefin epoxidation by oxo-iron porphyrins. Direct observation of an intermediate.
TL;DR: The present work believes it has generated and trapped the elusive cyclopropen-3-yl radical and has determined its symmetry and gross structure, demonstrating the power of modern a b initio M O methods.
