Abstract

Green chemistry, also called sustainable chemistry, is an important area of chemistry as well as chemical engineering that focused on the designing of catalyst or the processes that minimize the use and generation of hazardous substances. To maintain the sustainable production of chemicals in any modern industrial processes it requires high efficiency in any catalytic reactions, by minimizing by-products and wastes also at the same time the metal which is used as a catalyst should be cheaper, earth-abundant, environmental friendly and non-toxic in nature. Thus introducing this earth-abundant metals as a novel catalyst, allows us to readily access a host of applications with lower environmental impact. Chemistry of main group metals are less developed and need to explore more. Due to earth abundant in nature of the alkaline-earth metals and aluminum metal, make it inexpensive, easily accessible along with its low toxicity and biocompatibility make it attractive for various type of application in chemical synthesis. Additionally, it can able to show as a versatile catalyst for a broad spectrum of reactions including polymerization reactions of cyclic esters, styrene and dienes, epoxidation of alkenes, hydrofunctionalization reactions and also atom economical reaction, cross-dehydrocoupling of silanes and amines, hydroelementation (such as hydroamination, hydrophosphination, hydrosilylation and hydroboration) reactions of unsaturtarated moieties such as carbonyl compounds, alkenes and alkynes etc. In my dissertation work, I have primarily focused on the syntheses and structural characterization of well-defined homo- and heteroleptic main group metal complexes supported by functionalized phosphinamino chalcogenide ligands in their coordination sphere as multi-dentate chelating ligands. All newly prepared homoleptic and heteroleptic metal complexes were utilized as active pre-catalysts in atom economical reactions such as ROP of cyclic ester Cross-dehydrocoupling reactions and hydroelementation (hydroboration) reactions.
