“…Some molybdates show antiviral, antitumoral or antibiotic activity [5][6][7]. They are also known as efficient catalysts for the oxidation of various organic compounds with different oxygen donors like ROOH [8][9][10][11][12][13][14][15][16][17][18][19][20] and H 2 O 2 [21][22][23][24][25][26][27][28][29]. Molybdenum(VI) dioxo or oxodiperoxo compounds are commonly encountered in oxidation catalysis.…”

Molybdenum Complexes as Catalysts for the Oxidation of Cycloalkanes with Molecular Oxygen

A group of new polymolybdates was synthesized and tested in the catalytic oxidation of cycloalkanes. Investigated compounds exhibit broad structural diversity including polymolybdates with isolated anionic clusters (0-dim), polymeric anions (1-dim), Mo-O layers (2-dim) as well as hexagonal and orthorhombic molybdenum oxides (3-dim). All studied molybdenum complexes were found to be active in the reaction conditions yielding ketones and alcohols as main products. In the case of layered compounds (2-dim), dicarboxylic acid was detected in the mixture of reaction products. The structure of investigated molybdenum compounds was shown to have influence on yields and selectivities of the investigated reactions. Anionic layers separation (in 2-dim materials) as well as type and charge of organic cations present in the compounds are prime examples of structural factors influencing the oxidation reactions efficiencies. On the basis of obtained results and literature reports a mechanism for the oxidation of cycloalkanes by polymolybdates has been proposed. Graphical Abstract

“…accommodates the bidentate ligands by forming oxomonoperoxo complexes of the type [MO(O 2 )(bidentate) 2 ] (the bold font indicates bulky ligand) [6][7][8]. Recently, it has been shown that the MoO(O 2 ) 2 cores with bidentate ligands are useful catalysts in the epoxidation of olefins [6][7][8][9][10]. Epoxidation of olefins and arenes is an important transformation in organic synthesis since the epoxy compounds are widely used, for example in the manufacture of polyurethanes, unsaturated resins, glycols, surfactants, etc.…”

MoO(O 2 ) 2 (PyCOXH)(H 2 O)] and PMePh 3 [Mo-O(O 2 ) 2 (PyCO)] (PyCOXH = Pyridine-2-carboxaldoxime and PyCOH = Pyridine-2-carboxylic acid) have been synthesized.Both complexes have been characterized by physico-chemical and spectroscopic methods; in addition, the carboxylate complex has been structurally characterized by X-ray crystallography. The carboxylate complex is a more efficient catalyst than the oxime complex for epoxidation of olefins and shows excellent catalytic activity for the substrates: cyclooctene, cinnamyl alcohol, allyl alcohol and 1-hexene.

The oxidation of alcohols to carbonyl compounds is one of the most fundamental reactions in synthetic organic chemistry. In order to achieve the realization of dehydrogenation reactions with high atomic efficiency, suitable catalysts and oxidants are considered as the key factors to obtain the optimum activity and aldehydes/ketones selectivity. This review aims to make an overview on the reasonable reaction mechanism and promising catalytic system of alcohols dehydrogenation.
