1-Cyclohexenyl trifluoromethanesulfonate is an enol triflate used as a key intermediate in organic synthesis. It is particularly employed in transition-metal-catalyzed cross-coupling reactions, such as Suzuki, Negishi, and Heck couplings, where the triflate group acts as an excellent leaving group to form diversely substituted cyclohexene derivatives. This compound is crucial for constructing complex organic molecules, including pharmaceuticals, agrochemicals, and advanced materials, by enabling regioselective functionalization at the vinyl position. Additionally, it is utilized in catalyst development and polymer modification to impart specific properties like improved reactivity or solubility.
