CYANOSELENYLATION OF KETENE ACETALS. SYNTHESIS OF CARBONYL-PROTECTED α-OXO CARBONITRILES

Article abstract of DOI:10.1246/cl.1982.1733

The reaction of ketene acetals with phenyl selenocyanate afforded a new type of compounds, α,α-dioxy-β-phenylseleno carbonitriles (carbonyl-protected α-oxo carbonitriles), in good yields.Oxidation of these vicinalcyanoselenenylation products gave β,γ-unsaturated α,α-dioxy carbonitriles in excellent yields.
