The use of palladium catalysts for the oxidation of alcohols to aldehydes and ketones in the presence of various types of reoxidants is well known. Recently, the advantages of using molecular oxygen as the oxidant in the Pd-catalyzed oxidation of alcohols have been explored. The aim of this review is to provide an overview on the most important homogeneous palladiumcatalyzed aerobic oxidation o...

A series of transition metal complexes with two thiosemicarbazide Schiff bases, 1-(4-dimethylaminobenzyl- idene)thiosemicarbazide (ABTSC) and 1-(2-pyridincarboxyl-idene) thiosemicarbazide (TCTS) were synthesized with Co(II), Ni(II), Zn(II), Cd(II) and Ag(I) salts (chloride and acetate). These complexes were characterized by different methods including proton nuclear magnetic resonance (1HNMR),...

 The catalytic air oxidation-trimerization of alcohols was carried out with hetropolyacids. In the presence of hetropolyacid formation of cyclotrimers of alcohols and aldol condensation products ...

Efficient and selective oxidation of alcohols with NaIO4 catalyzed by an organic-inorganic hybrid material in which manganese(III)5,10,15,20-tetrakis(4-aminophenyl)porphyrin chloride, MnIII(TAPP)Cl, is covalently linked to a Lindqvist structure of polyoxometalate, Mo6O192-, at room temperature is reported. The effect of various parameters such as catalyst amount, solvent and oxidant were studie...

a mild, efficient and fast method for the oxidation of alcohols and trimethylsilyl and tetrahydropyranyl ethers to their corresponding carbonyl compounds using cro3 in the presence of sulfonic acid functionalized ordered nanoporous na+-montmorillonite (sanm) and under solvent-free conditions is reported. all reactions were performed at room temperature in high to excellent yields. ease of the p...

Manganese metal-organic framework (Mn-MOF) containing Mn2+ ions, benzenetricarboxylic acid (BTC) and N,N-dimethylformamid (DMF) was prepared and used as catalyst for oxidation of alkenes such as 1,1-diphenylethylene, trans-stilbene, cyclohexene, norbornene, styrene and cyclooctene to epoxides with 33-92% conversion and 75-100% selectivity and oxidation of alkanes such as fluorene, adamantane, e...

an efficient protocol for the selective oxidation of primary alcohols to aldehydes withh5io6/v2o5 in ionic liquid [bmpy][pf6] has been developed. high yields of the products, mildreaction conditions and simple experimental procedure make this protocol complementary tothe existing methods. the catalyst can be reused for several times without obvious loss of thecatalytic activity.
