Bis(heptafluorobutyryl) peroxide (1) smoothly reacted with furans and thiophenes under mild conditions to regioselectively give 2-perfluoropropylfurans and thiophenes in high yields. Mechanistically, reactions with furans or thiophenes are considered to be initiated by one-electron transfers from substrates to 1. On the other hand, the perfluoropropylation of pyridine was proceeded by the usual free-radical
双(七氟丁酰)过氧化物 (1) 在温和条件下与呋喃和噻吩顺利反应,以高产率区域选择性地得到 2-全氟丙基呋喃和噻吩。从机制上讲,与呋喃或噻吩的反应被认为是由从底物到 1 的单电子转移引发的。 另一方面,吡啶的全氟丙基化是通过通常的自由基取代吡啶鎓盐来进行的1的均分解
