Silica-supported Poly-γ-aminopropylsilane Cu^(2+)-Pd^(2+) Complex: A New Catalyst System for Heck Vinylation Reaction

摘要

In this paper, a new silica-supported poly-γ-aminopropylsilane Cu^2+-Pd^2+ 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.
