Separable Suzuki

摘要

There is no shortage of palladium catalysts available to a chemist planning a Suzuki cross-coupling - a number of commercially available complexes are available (with Pd(PPh3)4 being perhaps the best known) and many more tailor-made systems reported in the literature. As with many homogenous systems, however, product isolation and metal contamination can be a concern. And although there are many successful heterogeneous systems, common problems such as metal leaching, aggregation, and deactivation are wellknown issues. Now, Javier Pérez-Ramírez and co-workers have attempted to bring together the best of both of these worlds by synthesizing heterogeneous single-atom palladium catalysts.
