Selective palladium-catalyzed hydroformylation of alkynes to α,β-unsaturated aldehydes.


Atom-efficient: A selective palladium catalyst system is used for the hydroformylation of alkynes (see picture). In this syngas reaction, various alkynes were smoothly transformed to synthetically interesting α,β-unsaturated aldehydes in good yields with high regio- and stereoselectivity.
