Abstract
Polyamidoamine dendrimers, constructed on the surface of silica, were phosp honated using diphenylphosphinomethanol (prepared in situ) and complexed to form a palladium-dimethyl TMEDA complex. This catalyst was found to be eff ective in the Heck reaction of aryl bromides with both butyl acrylate and s tyrene, affording coupling products in moderate to good yields. The heterog eneous palladium catalyst can also be recycled and reused with only moderat e reduction in activity.
