In this regard, the alkaline earth metal complexes have attracted significant attention. Herein, we have used a beta-diketiminato ligand with methyl-pyridine side arm to synthesize magnesium (1) and calcium (2) compounds. The constitutions of 1 and 2 have been confirmed by single crystal X-ray studies, which show that the magnesium and calcium atom in 1 and 2 possesses octahedral geometry. Subsequently, we have used them as catalysts (1 mol %) for hydroboration of a wide range of aldehydes using pinacolborane (HBpin) at room temperature. The strategy has further been extended to ketones with 2 mol % catalyst loading. DFT calculations have been performed to understand the mechanism.</p>1 aYadav, Sandeep1 aDixit, Ruchi1 aBisai, Milan, Kumar1 aVanka, Kumar1 aSen, Sakya, S.  uhttps://library.ncl.res.in/content/alkaline-earth-metal-compounds-methylpyridinato-beta-diketiminate-ligands-and-their
