New application of indium catalysts: A novel and green concept in the fine chemicals industry
Abstract:
New industrially important catalytic processes for application in the fine chemicals industry (e.g., synthesis of vitamins and key-intermediates) are presented. Protocols with indium catalysts provide the advantages of high selectivity and low catalyst loading for Friedel-Crafts-type alkylation, Wagner-Meerwein rearrangement, and acylation reactions. The transformations discussed could be carried out in a continuous manner.
