Electrochemical Wacker oxidation of terminal olefins has been among the most interesting reactions from an industrial standpoint. However, the poor regioselectivity and contamination of products with palladium (Pd) catalysts have been the main drawbacks of its commercialization. Herein, rational preparation, as well as catalytic, structural, and electrochemical properties analysis of solid-supported Pd on graphene nanoplatelets (GNP) highly active catalysts for regioselective Wacker-type electrooxidation of terminal olefins is presented. The prepared catalysts improved by two orders of magnitude the electrocatalytic oxidation of 1-octene compared to the conventional homogeneously-catalyzed reactions. The control over oxidation regioselectivity via minimization of the cathodic reduction reaction was also confirmed.To be presented at: the 235th ECS Meeting, Dallas, TX. May 26-31, 2019.

This review article focused on the innovative procedure for electrophilic fluorination using HF and in situ generation of the required electrophilic species derived from hypervalent iodine compounds. The areas of synthetic application of this approach include fluorination of 1,3-dicarbonyl compounds, aryl-alkyl ketones, styrene derivatives, α,β-unsaturated ketones and alcohols, homoallyl amine and homoallyl alcohol derivatives, 3-butenoic acids and alkynes.

Hypervalent iodine compounds have proved to be very useful reagents to bring about various oxidative transformations including (i) α-functionalization of carbonyl compounds, (ii) oxidation of phenols, and (iii) oxidative rearrangement of ketones and α,β- unsaturated ketones. These reactions find interesting applications in the development of newer and convenient approaches for the synthesis of flavonoids. This review focuses on the use of most common three hypervalent compounds, namely iodobenzene diacetate, [hydroxy(tosyloxy)iodo]benzene, and [bis-trifluoroacetoxy(iodo)]benzene in the synthesis of cis/trans-3-hydroxyflavanones, 3-hydroxyflavones (flavonols), flavones, isoflavones and related compounds.
