Tetratrifylpropene (TTP) has been developed as a highly acidic, allylic C-H acid for Bronsted and Lewis acid catalysis. It can readily be obtained in two steps and consistently shows exceptional catalytic activities for Mukaiyama aldol, Hosomi-Sakurai, and Friedel-Crafts acylation reactions. X-ray analyses of TTP and its salts confirm its designed, allylic structure, in which the neg. charge is delocalized over four triflyl groups. NMR experiments, acidity measurements, and theor. investigations provide further insights to rationalize the remarkable reactivity of TTP.
