    • Abstract DAB- dendr -(NH 2 ) 32 has been modified to produce two novel dendrimeric P , N -ligands, DAB- dendr -[1,2-(NCHC 6 H 4 PPh 2 )] 32 and DAB- dendr -[1,2-(NHCH 2 C 6 H 4 PPh 2 )] 32 . These were both found to activate electron rich aryl bromides in the Heck reaction. The reactions seem to proceed better in a novel solvent system consisting of an equimolar mixture of a tertiary amine with acetic acid. A marked dependence of the conversion on the [equivalents of dendrimeric ligand]/[Pd… CONTINUE READING
