Solid supported catalysts have been of considerable interest in organic synthesis for last few years. Solid support provides an efficient heterogeneous catalytic system owing to facile recovery and extensive recycling by simple filtration because of possessing 3-R approach (Recoverable, Robust and Recyclable) and makes solid supported catalyst more appealing nowadays. In view of the high cost and shortage of furthermost used palladium catalyst, its recovery and recycling are vital issues for any large-scale application which are being overcome by using solid supported catalytic systems. Therefore, a variety of inorganic and organic solid-supported catalytic systems have been developed so far in order to address these challenges. This review attempts highlight a number of solid supported catalytic systems in the pro-active area of widely used C−C cross coupling reactions.
