Abstract
Heterogeneous palladium nanoparticle catalysts that are supported on amphiphilic carbon spheres (Pd@ CSP) have been utilized for water-mediated Heck coupling reactions of aryl halides with different alkenes under phosphine free as well as aerobic conditions. Furthermore, a variety of Heck coupling reactions using different bases and solvents, including organic polar and non-polar solvents, have been explored. Aryl bromides are ...
