| 英文摘要 | A series of novel gemini dicationic acidic ionic liquids (gdails), compounds 1-3 carrying two so(3)h groups at the cation moieties and having anions of the type cf(3)so(3)(-), were synthesized in good yields (scheme 1). some physicochemical properties of 1-3 were determined: due to their unique structures, these novel gdails showed noticeable hydrophilic properties and strong acidities (table 1). beckmann rearrangements of oximes catalyzed by 1, 2, or 3/zinc chloride (gdail/zncl(2)) were investigated (scheme 2), the corresponding amides were formed in up to 99% yield in the presence of 5 mol-% of gdail/zncl(2) catalyst under optimized conditions (tables 2 and 3). the peculiar solubilities of 1-3 made the separation of the catalysts from the products very facile, and the catalytic system could be recycled and reused for three times. |
