An efficient conversion of olefins to ketones was achieved by the use of molecularoxygen and triethylsilane in the presence of a catalytic amount of cobalt(II) complex of porphyrin. The oxidation was accelerated remarkably in alcohols and had chemoselectivity for conjugated olefins.
在催化量的卟啉钴 (II) 络合物存在下,通过使用分子氧和三乙基硅烷,实现了烯烃到酮的有效转化。在醇中氧化显着加速并且对共轭烯烃具有化学选择性。
Direct hydroperoxygenation of conjugated olefins catalyzed by cobalt(II) porphyrin
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
