Recent Progress of Calcium-Based Catalysts in Organic Transformations

This article aims to draw the attention of the scientific community toward the use of calcium-based reagents in various organic transformations. These complexes are capable of activation and nucleophilic addition of olefins, carbonyls, nitro groups of catalysts, epoxides, methyl aromatics and alcohols. These complexes are capable of activating different functional groups for nucleophilic addition to alkene, carbonyl, nitro, epoxide, methylarene and alcohol groups. Calcium-based catalysts have broad tolerance to substrates, reaction pathways, and appear to be sustainable alternatives to transition metals, rare earth metals, for a variety of organic transformations. The scope of this review is limited to catalytic alterations mediated by calcium complexes. This is the first broad review article that covers all aspects of calciummediated reactions up to the year 2022.
