Serendipity in perfluorinated series: unexpected synthesis of 7-(perfluoroalkyl)-2,3-dihydro-5 H -1,4-dioxepin-5-one
摘要:
Treatment of [2-(perfluoroalkyl)-1,3-dioxolan-2-yl]acetic acids with thionyl chloride and a 48% HBr solution yields 7-polyfluoroalkyl-2,3-dihydro-5H-1,4-dioxepine-5-one. The production of this unexpected entity is explained by a rearrangement mechanism proposed in this work. (C) 2001 Elsevier Science Ltd. All rights reserved.
