Pd-catalyzed C-C bond forming reactions have attracted huge interest
not only among the synthetic organic chemists but researchers of various
disciplines for over two decades because a large panorama of value added
organic target molecules can be designed employing this synthesis protocol.
Richard F. Heck, Ei-ichi Negishi and Akira Suzuki have been awarded the
Nobel Prize in Chemistry 2010 for their pioneering works on these palladiumcatalyzed
cross-coupling reactions in organic synthesis. More greener and
eco-friendly synthetic conditions together with the recyclability of the Pdcatalyst
have been continuously hunted over the years. It is essential to know
the different steps and mechanism involved in these C-C coupling reactions
together with the active Pd-sites present at the catalytic surfaces. In this
review we have focused on discussing various protocols involved in the C-C
coupling reactions and gradual developments in Pd-grafted functionalized
mesoporous materials. Recyclability and sustainability of the catalyst along
with their surface modification strategies have been discussed. Catalytic
efficiency of these functionalized mesoporous materials largely depends on
strong binding of the Pd-sites with the support matrix. Thus, discussion on
different types of supports has also been made.
