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

Cross-coupling arylations of cyclic β-promo α,β -unsaturated aldehydes were carried out with triarylbismuths as atom-efficientmulticoupling organometallic reagentsunder palladium-catalyzed conditions. These reactions afforded the corresponding arylated alkenes in an efficient manner with good to high yields.
