Abstract
Abstract o-Benzenedisulfonimide turns out to be a highly efficient Brønsted acid catalyst for the acylation of a number of alcohols, phenols, and thiols under a metal-and solvent-free procedure; reaction conditions are mild and yields very good. After the workup, the catalyst can be easily recovered and purified, ready to be reused, with economic and ecological advantages.
