A synergetic cocatalytic effect provided by an iodonium salt in the base-catalyzed Knoevenagel condensation has been found. The diphenyliodonium triflate serving as the halogen bond-donating Lewis acid provides the higher cocatalytic effect than zinc(II) triflate or triflic acid serving.
已经发现碘鎓盐在碱催化的诺文纳格尔缩合反应中具有协同助催化作用。用作提供卤素键的路易斯酸的二苯基碘鎓三氟甲磺酸盐提供比三氟甲磺酸锌(II)或三氟甲磺酸锌更高的助催化效果。
