We have reported an aerobic oxidation of primary and secondary alcohols to respective aldehydes and ketones using a bipyridyl-cinchona alkaloid based palladium catalytic system (PdAc-5) using oxygen at moderate pressure. ThePdAc-5catalyst was analysed using SEM, EDAX, and XPS analysis. 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 commercially 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 commercial catalysts, solvent systems, mixture of solvents, and catalyst mole%, were conducted usingPdAc-5. The synthetic strategy of oxidation of alcohol into carbonyl compounds was well established and all the products were analysed using1H NMR,13CNMR and GC-mass analyses.

The invention discloses a method for synthesizing furacilin under catalysis of a supported catalyst and belongs to the field of chemical synthesis. A 5-nitrofurfural intermediate is synthesized from furfuryl alcohol used as a raw material through steps of esterification, nitration, deprotection, oxidation and the like, and then, 5-nitrofurfural and semicarbazide are subjected to a condensation reaction under the catalytic action of the supported catalyst CuO/CNTs to produce furacilin. The method is simple to operate, the adopted catalyst has the characteristics of being non-toxic, easy to remove and renewable, and the product yield is high.
