Used as a highly reactive benzoylating agent in organic synthesis, particularly for the introduction of the benzoyl group to alcohols, phenols, and amines under mild conditions. Its strong electrophilic character makes it effective in acylation reactions where traditional reagents may fail. Commonly employed in the preparation of esters and amides in pharmaceutical and agrochemical intermediates. Also utilized in Friedel-Crafts acylation reactions due to its ability to generate acylium ions readily. The presence of the triflate leaving group enhances its reactivity, allowing for efficient transformations even at low temperatures. Suitable for sensitive substrates in complex molecule synthesis.
