Silica-supported Poly-γ-aminopropylsilane Cu2+-Pd2+ Complex:A New Catalyst System for Heck Vinylation Reaction
In this paper, a new silica-supported poly-γ-aminopropylsilane Cu2+-Pd2+ complex was studied in Heck vinylation reaction of aryl iodide with olefins. The catalyst is highly active and stereoselective at 70-100 ℃, and can be resused after washing without loss in activity.
