Oxidation of Benzyl Alcohol by a Dioxo Complex of Ruthenium(VI).
TL;DR: The kinetics and mechanism of reduction of trans-[Ru(VI)(tpy)(O)(2)(L)](2+) by benzyl alcohol have been studied in water and acetonitrile and mechanisms are proposed involving prior coordination of the alcohol followed by O insertion into a benzylic C-H bond.

Oxidation of methoxybenzenes to p-benzoquinones catalyzed by methyltrioxorhenium(VII)
TL;DR: In this paper, an arene oxide mechanism was proposed for the formation of p-benzoquinones, which would account for the participation of the acid and also overoxidation by cleavage of the isne oxide ring with hydrogen peroxide.

Mechanism of oxidation of organic sulphides by oxo(salen)manganese(v) complexes
Arunachalam Chellamani,N. M. I. Alhaji,Seenivasan Rajagopal,Ranganathan Sevvel,Chockalingam Srinivasan +4 more
TL;DR: The second-order kinetics of oxygen atom transfer from several cationic oxo(salen)manganese(V) [salen = N,N′-ethylenebis(salicylidineaminato)] complexes to organic sulphides have been studied spectrophotometrically in acetonitrile at 25 °C as mentioned in this paper.

TL;DR: A series of N₂L(n) tripodal tetradentate ligands derived from di-/tetra-tert-butyl substituted 2-[bis(2-hydroxybenzyl)aminomethyl]X (X = pyridine and benzimidazole) and 8[bis(3,5-di-terrt- butyl-2-HydroxybenZyl)]aminoquinoline (H�

TL;DR: In this paper, the solid-state structure of the free ligand oep-H2saldpen was determined by single crystal X-ray diffraction, and the vibrational spectra of the molybdenum complexes were supported by carrying out ab initio calculations for the possible isomers using [MoO2(salen)] and MoO2Cl2(H2salen) as model compounds.
