Nevertheless, most of the competent metal complexes till date are found to be noble or late transition metal (Rh, Ru, Ir, Pd etc.) complexes. To circumvent the limited availability of this kind of fast depleting metals, non-noble or early transition metals (Mn, Fe, Co) are gaining severe attention in all kind of fields of catalysis. Recent work on non-noble metal catalysis has shown the potential of tridentate ligands (achiral and chiral) in a number of transformations, including the asymmetric ones. Based on these considerations, various Phosphine-containing tridentate, planar chiral ligands based on ferrocene scaffold (e.g.- PNN, PNP, PSP, PSN etc.) were designed. Various organic and organometallic reactions were thoroughly explored, during the course of multistep ligand synthesis processes. A large number of new organic and ferrocenyl compounds were isolated by chromatographic separations and crystallizations; and also, fully characterized (multinuclear NMR, HRMS, XRD diffraction analysis on monocrystals, etc)."
