Various α,β-unsaturated carbonyl compounds, such as α,β-unsaturated esters, α,β-unsaturated ketones, α,β-unsaturated nitriles, and α,β-unsaturated amides, were directly converted to the corresponding a-hydroxyimino carbonyl compounds in high yields on treatment with butyl nitrite and phenylsilane in the presence of a catalytic amount of N,N′-bis(2-ethoxycarbonyl-3-oxobutylidene)ethylenediaminatocobalt(II) complex under mild conditions.

This novel method efficiently converts,-unsaturated carbonyl compounds to a-hydroxyimino carbonyl compounds in high yields using butyl nitrite and phenylsilane under mild conditions, offering potential applications in various industries.
