Four-Component Reaction of Sodium Nitrite, Aromatic Alkenes, P₄S₁₀, and Alcohols Leading to β-Oximino Phosphorodithioates

A simple and efficient strategy has been developed to access β-oximino phosphorodithioate through additive-free four-component reactions of sodium nitrite, aromatic alkenes, P 4 S 10, and alcohols. The present reaction was carried out under mild conditions through a positive ion process. A series of β-oximino phosphorodithioates could be obtained in moderate to good yields by employing sodium nitrite as a promoter and an oxime source.
