Clay Catalyst in Organic Synthesis

Clay and Modified clays are very useful for different type of reaction, like FC-alkyalation, Rearrangement, oxidation, Nitration, Esterification, Reduction etc. Clays are react as Acid or Base like Bronstate and Lewis Acid or Base. Clay has both characteristics acid & base. Catalyst having good surface activity, cationic-anionic ion exchange capacity. There are some reaction and how it occurs given here.
