Cellulose supported palladium(0) catalyst for Heck and Sonogashira coupling reactions

Cellulose supported palladium(0) catalyst was prepared and applied for the Heck and Sonogashira coupling reactions by treating aryl iodides with alkenes and phenylacetylene, respectively, to afford corresponding coupled products in good to excellent yields. The catalyst was recovered by simple filtration and reused for several cycles. (c) 2006 Elsevier B.V. All rights reserved.
