Acrylonitrile, Vinyl cyanide
Acrylonitrile is a hydrogen acceptor. See also: crotononitrile
A silver-free palladium-catalyzed dehydrogenative phosphorylation of terminal alkynes with hydrogen phosphine oxides produces the corresponding value-added alkynylphosphine oxides in very good yields. This reaction could be easily conducted at gram scales without any decrease of efficiency.
