WebDec 30, 2024 · Tetrafluorothiophene S,S-dioxide has been found to be a powerful and versatile cycloaddend that undergoes a wide range of reactions as a Diels-Alder diene, dienophile, and [2 + 2] addend. Because it dimerizes only slowly at high temperatures, a broad range of conditions are available for these transformations. Reactions with … WebThis is the first example of spontaneous migration of a cycloaddend from one 6 ∶ 6-bond to another on the same fullerene cage surface. The UV/VIS spectrum of 1 is significantly different from that for C 60 F 18, suggesting that some electronic interaction may exist between the addend and the cage.
