Supported Dendritic Catalysts for Carbonylation, Hydroesterification, Oxidation, and Heck Reactions

Supported Dendritic Catalysts for Carbonylation, Hydroesterification, Oxidation, and Heck Reactions 

These palladium-functionalized dendrimers show selectivity for the linear reaction product. A drop in activity was found when the catalysts were reused (1-decene as substrate/G(4)Pd(PPh3)2 dendrimer as catalyst 92, 75, 73, and 45% yield for the first, second, third, and fourth, respectively). The (dba)Pd-PPh2-PAMAM-Si02 dendrimers of generations 0—4 showed activity for the oxidation of terminal alkenes under mild conditions. The catalytic activity was found to be dependent on
