[摘要]:The Beckmann rearrangement of a variety of ketoximes was carried out in imidazolium-based ionic liqs. in the presence of catalytic amts. of 2,4,6-trichloro[1,3,5]triazine. This mild and green procedure is highly regioselective affording the corresponding N-substituted amides in very good to quant. yields. The ionic liqs. were easily recovered and recycled several times. |
