Over the past few years, the use of heterogeneous catalytic systems has been preferred to homogeneous
counterparts because of their practical benefits such as convenient separation from the reaction mixture and reusability
of the catalysts in successive reaction runs which could improve the environmental, economic and sustainability
factors of organic reactions. Thus, attempts have been directed to develop varied solid catalyst supports to
improve the efficiency and recovering ability of the prepared catalysts while minimizing the deterrent effect of the
bulky supports in catalyst activity. Among this, ordered mesoporous silica materials have attracted considerable interest
owing to their noteworthy and desirable properties for catalytic applications such as high specific surface
area, accessible pore volume, tunable pore size and easy functionalization. Because of the great significance of C-C coupling reactions,
the main goal of this review is specifically focusing on the application of supported metal catalysts on both ordered mesoporous silica
(OMS) and periodic mesoporous organosilica (PMO) in C-C couplings.
Keywords: Ordered mesoporous silica, periodic mesoporous organosilica, C-C coupling, supported catalyst, Suzuki, Heck, Sonogashira.
