Oxidation of α,β-unsaturated aldehydes with hydrogenperoxide catalysed by benzeneseleninic acids and their precursors has been investigated. Bis 2-nitrophenyl diselenide has proved to be the most effective catalyst. The major products resulting from the oxidation are vinyl formates (a) which on hydrolysis give saturated aldehydes or ketones (g) having the carbon chain shortened by one carbon atom
A method for acylation of an aromatic compound, comprising reacting an aromatic compound and an acylating agent of the carboxylic acid type, in the presence of a Lewis acid and of a silylated reagent selected from the group consisting of halosilanes and halosiloxanes.
