FERRIC HYDROGENSULFATE AS AN ACIDIC AND SOLID SUPPORTED CATALYST IN ORGANIC SYNTHESIS: A REVIEW

Abstract

Ferric Hydrogensulfate (FHS) has been used in many organic procedures as a solid acid catalyst. FHS is an inexpensive catalyst and prepared by simple process. It is easy to store, handle, eco-friendly with high reactivity and reusability. It is used in various organic preparations to give corresponding product in excellent yield with high selectivity. FHS supported on silica is known as Silica supported Ferric Hydrogensulfate (SFHS) which is also used as acidic catalyst for various organic transformations. Some important applications of FHS and SFHS in organic reactions are discussed in this review.
