Catalyst-Controlled Selectivity in Oxidation of Olefins: Highly Facile Success to Functionalized Aldehydes and Ketones

The attractive challenge in green chemistry is exploring novel heterogeneous catalyst system for catalyst-controlled product selectivity for oxidation of olefins. Hence, we proposed efficient and green catalytic methods for the selective synthesis of aldehydes and ketones, the selectivity of the reaction is exclusively dependent on the metals from the catalyst. A series of novel glycosyl pyridyl triazole-platinum (GPT-Pt) complex have been successfully synthesized and fully characterized for the first time. The GPT-Pt catalysts have been applied in the selective oxidative cleavage of alkenes to yield the corresponding aldehydes in the presence of H 2 O 2 as an oxidant in water. With GPT-Pd as the catalyst, the oxidation reaction give the ketones as the main products. Moreover, the catalysts were recovered and reused six times without significant yield decrease. Graphical Abstract Novel glycosyl pyridyl triazole-platinum (GPT-Pt) complex have been successfully synthesized.The selective synthesis of aldehydes or ketones is exclusively dependent on the metals from the catalyst. Moreover, the catalysts can be separated and reused at least six times with superior activity.
