The vinylation of iodobenzene with methyl acrylate was studied using palladium-based heterogeneous catalysts. Methyl cinnamate was formed as vinylation product and benzene as side product. All catalysts were of the type Si02-X-(NH),-Pd-L2, where L = P( C,H5)3 or C,HsCN and X = Sn, Al or Ti. The cata
The use of reverse phase controlled-pore glass beads in Heck reactions affords the products with low levels of palladium leaching. Additionally, an enantioselective palladium catalysed allylic substitution reaction has been achieved with high enantiomeric excess and a low level of leaching
