Direct hydroperoxygenation of conjugated olefins catalyzed by cobalt(II) porphyrin

Abstract

A novel and direct synthesis of hydroperoxy compounds from various types of conjugated olefins was established via cobalt(II) porphyrin-catalyzed hydroperoxygenation. The reaction of α,β,γ,δ-unsaturated carbonyl compounds, acrylic esters, α-substituted acrylic esters and styrene derivatives with molecular oxygen and triethylsilane in the presence of a catalytic amount of cobalt(II) porphyrin proceeded rapidly to give the corresponding hydroperoxygenated compounds in high or moderate yields.
