Our group focuses on the ‘Directing Group’ free C-H functionalization through ‘Carbene Transfer’ reactions using novel transition metal or organometallic complexes as catalysts. The relatively inert nature of the strong C-H bond demands the syntheses of specially designed sophisticated catalysts for this method to be employed as the sustainable route for a diverse array of synthetic transformations. One of the major challenges of C-H functionalization is to attain the regioselectivity as there are multiple C-H bonds present in the same molecule. The most effective way of attaining this selectivity is by introducing a directing group which offers a chelating effect to bring the catalyst/reactant to the close proximity of the desired site. The disadvantage of using the directing group is the ultimate fate since in most of the cases it is not a desired moiety in the final molecule of the interest. Therefore, we design the catalyst in an effective way by introducing an amicable steric and electronic environment which can nullify the need of the directing group to attain the regio- and stereoselectivity.
