We wish to report the reactions of conjugated dienes with I(py)2BF4. This simple and general method allows the regiospecific 1,2-addition of iodine and a nucleophile to terminal dienes and the 1,4-addition to internal dienes.
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
Synthesis of γ-hydroperoxy-α,β-unsaturated carbonyl compounds from α,β,γ,δ-unsaturated carbonyl compounds by cobalt(<scp>II</scp>) porphyrin-catalysed hydroperoxygenation
γ-Hydroperoxy-α,β-unsaturated carbonyl compounds are prepared in good yields by the regioselective hydroperoxygenation of α,β,γ,δ-unsaturated carbonyl compounds with molecular oxygen and triethylsilane in the presence of cobalt(II) porphyrin as a catalyst.
