Since the start of the 21st century an increasing interest is shown by various research groups in common alkali metal (Li, Na, K) and heavier alkaline earth metal (Ca, Sr) based catalysts owing to the low toxicity and inexpensive compared to those of transition metals and lanthanides, and the availability everywhere on earth’s crust and in the ocean’s water which make them attractive and sustainable elements for potential use in a multitude of transformations even though their redox chemistry and the number of oxidation states are limited. In present-day synthetic organic chemistry, the adoption of atom-economical and eco-friendly chemical processes is one of the most essential topics in research. In particular, finding relatively less toxic and harmless alternatives for metals that have toxic and detrimental effects on the environment is highly desirable. Furthermore, the use of abundant metals is encouraged, rather than rare metals, because of the latter’s potential for becoming depleted in the future. Our ongoing research focuses to develop and study the structures of various alkali and alkaline earth metal complexes using suitable multi-dentate ligands. We also have explored the catalytic application of these complexes in different organic transformation such as hydroboration, hydrophosphination/hydrophosphorylation, hydrosilylation, hydrogenation, cross dehydrocoupling, polymerization etc. under ambient condition. The highlights of these work will be presented.
