Almendros, Pedro published the artcileTransition metal-free controlled synthesis of bis[(trifluoromethyl)sulfonyl]ethyl-decorated heterocycles, Recommanded Product: 1-Methylpyrazole, the publication is Organic Chemistry Frontiers (2018), 5(21), 3163-3169, database is CAplus.
Several heterocycles reacted with shelf-stable 2-(2-fluoropyridinium-1-yl)-1,1-bis[(trifluoromethyl)sulfonyl]ethan-1-ide, a latent Tf2C=CH2 source, to give rise in a mild and controllable way to adducts via direct C-H bis[(trifluoromethyl)sulfonyl]ethylation reactions. This metal- and irradiation-free protocol is convenient. Besides, the volatile side-product 2-fluoropyridine can be smoothly eliminated under vacuum, which facilitates purification The substrate scope survey discloses that exquisite chemo- and regioselectivities are achieved in a variety of heterocyclic systems. Of particular interest are the late-stage structural modification of known pharmaceuticals, such as the marketed drugs phenazone (antipyrine) and edaravone, and the development of a water soluble fluorescent dye.
