UDCaT‐5: A Novel and Efficient Solid Superacid Catalyst for Claisen Rearrangement of Substituted Allyl Phenyl Ethers

Abstract

The Claisen rearrangement of allyl phenyl ethers is a fundamental reaction in organic synthesis with a variety of applications in perfumes, flavors, pharmaceuticals, agrochemicals, polymers, fine chemicals, and intermediate industries. The development of environmentally benign processes using solid acid catalysts is becoming an area of growing interest. It was accomplished in an efficient, economical, environmentally friendly manner and is 100% selective toward alllyl phenols by employing UDCaT‐5 as solid acid catalyst.
