Abstract: The polymeric graphitic carbon nitride (g-C3N4) has been one of the interesting
earth abundant elements. Though g-C3N4 finds application as a photocatalyst, its photocatalytic
behaviour is limited because of low efficiency, mainly due to rapid charge recombination.
To overcome this problem, several strategies have been developed including
doping of metal/non-metal in the cavity of g-C3N4. Moreover, the CoFe2O4 NPs have been
used in many organic transformations because of its high surface area and easy separation
due to its magnetic nature. This review describes the role of cobalt ferrite as magnetic
nanoparticles and metal-doped carbon nitride as efficient heterogeneous catalysts for new
carbon-carbon and carbon-hetero atom bond formation followed by heterocyclization. Reactions
which involved new catalysts for selective activation of readily available substrates
has been reported herein. Since nanoparticles enhance the reactivity of catalyst due to higher catalytic
area, they have been employed in various reactions such as addition reaction, C-H activation reaction, coupling
reaction, cyclo-addition reaction, multi-component reaction, ring-opening reaction, oxidation reaction and reduction
reactions etc. The driving force for choosing this topic is based-on huge number of good publications
including different types of spinels/metal doped-/graphitic carbon nitride reported in the literature and due to
interest of synthetic community in recent years. This review certainly will represent the present status in organic
transformation and for exploring further their catalytic efficiency to new organic transformations involving
C-H activation reaction through coupling, cyclo-addition, multi-component, ring-opening, oxidation and
reduction reactions.
