Pauson–Khand reactions catalyzed by entrapped rhodium complexes
An entrapped Rh complex prepared by a sol–gel process has been used as a catalyst in the Pauson–Khand reaction under mild reaction conditions; the catalyst is easily recovered and reused at least 10 times without losing catalyst activity.
