Used in organic synthesis as a hypervalent iodine reagent for selective oxidative transformations. Particularly effective in lactonization reactions, enabling the formation of five- and six-membered lactone rings from carboxylic acids and alkenes under mild conditions. Its fluorinated backbone enhances stability and reactivity, making it suitable for late-stage functionalization in pharmaceutical synthesis. Also employed in radical cyclization processes where iodine-mediated bond formation is required. Shows good chemoselectivity, minimizing side reactions in complex molecule assembly.
