Oxidation of benzyl alcohols to aldehydes and ketones under air in water using a polymer supported palladium catalyst

Synthesis, Characterization, and Relative Study on the Catalytic Activity of Zinc Oxide Nanoparticles Doped MnCO3, –MnO2, and –Mn2O3 Nanocomposites for Aerial Oxidation of Alcohols

“…In order to exploit the applicability of the present catalytic system and to generalize the scope of the oxidation process, the oxidation reaction has extended to various types of alcohol such as primary aromatic, allylic, heteroaromatic, and aliphatic alcohols. Generally, all primary aromatic alcohols could be oxidized rapidly to the corresponding aldehydes with complete conversions within very short reaction times (Table 6, entries [10][11][12][13][14][15][16][17][18][19][20][21][22]. Moreover, more than 99% selectivity to corresponding aldehydes has been achieved in most of oxidation reactions and no other products were detected in the reaction mixture because no overoxidation to carboxylic acids occurred.…”

“…Usually, conventional oxidation of alcohols was conducted using toxic and expensive stoichiometric oxidizing agents such as CrO 3 , KMnO 4 , NaClO, Na 2 Cr 2 O 7 , SeO 2 , and Br 2 and leads to producing harmful by-products [12,13]. In contrast, using clean and low cost oxidizing agents, such as aqueous hydrogen peroxide and particularly molecular oxygen to produce water, is the only side product and has gained growing interest from the sustainable and green chemistry point of views [14,15]. In this context, noble metals such as gold [16][17][18][19][20], palladium [21], platinum [22][23][24], ruthenium [25,26], and rhodium [27,28] have been used as a heterogeneous catalyst for the alcohol oxidation with high catalytic activities and selectivities.…”

Esterification, transesterification and hydrogenation reactions of polyunsaturated compounds catalyzed by a recyclable polymer supported palladium catalyst

“…A C C E P T E D Pd-pol pre-catalyst was successfully employed in several palladium promoted reactions [26,27,28,29,30,31,32,33,34,35]. In all cases, the pristine Pd(II) supported complex was reduced in situ under reaction conditions to Pd(0), forming palladium nanoparticles (NPs) (the real active species) immobilized onto the insoluble support (Pd-pol, Scheme 1) and stabilized by the macroporous and reticulated polymer matrix [36].…”

Comparative Catalytic Evaluation of Nano-ZrOx Promoted Manganese Catalysts: Kinetic Study and the Effect of Dopant on the Aerobic Oxidation of Secondary Alcohols

“…The catalytic oxidation of alcohols to carbonyl compounds is one of the most valuable and significant organic transformations in synthetic chemistry from the scientific and manufacturing perspective [1][2][3][4][5]. The oxidation products are significant intermediates in perfumes, confectionary, flameretardants, dyestuffs, cosmetics, agrochemical, and pharmacological industries [6][7][8][9].…”
