An aerobic oxidation of primary and secondary alcs. RCH2OH (R = 2-methylphenyl, cyclohexyl, naphthalen-1-yl, pyridin-4-yl, etc.) to resp. aldehydes RCHO and ketones RCO using a bipyridyl-cinchona alkaloid based palladium catalytic system (PdAc-5) I·2Br using oxygen at moderate pressure was reported. The PdAc-5 catalyst was analyzed using SEM, EDAX, and XPS anal. The above catalytic system is used in experiments for different oxidation systems which include different solvents, additives, and bases which are cheap, robust, non-toxic, and com. available on the industrial bench. The obtained products are quite appreciable in both yield and selectivity (70-85%). In addition, numerous important studies, such as comparisons with various com. catalysts, solvent systems, mixture of solvents, and catalyst mole%, were conducted using PdAc-5. The synthetic strategy of oxidation of alc. into carbonyl compounds was well established and all the products were analyzed.
From this literature《An aerobic oxidation of alcohols into carbonyl synthons using bipyridyl-cinchona based palladium catalyst》,we know some information about this compound(1762-34-1)Safety of 5,5′-Dimethyl-2,2′-bipyridine, but this is not all information, there are many literatures related to this compound(1762-34-1).
