For the first time, CuAAC reaction catalyzed by copper(II) nitrate and counter ion effect of various copper(II) salts are reported. Use of a novel copper complex 1, derived from the reaction of copper(II) nitrate with 5-acetyl-2-amino-6-methyl-4-(pyridin-3-yl)-4H-pyran-3-carbonitrile, facilitated the CuAAC reaction at room temperature with a catalyst loading as low as 1 mol% within a very short reaction
首次报道了硝酸铜(II)催化的CuAAC反应和各种铜(II)盐的反离子效应。使用源自硝酸铜 (II) 与 5-乙酰基-2-氨基-6-甲基-4-(吡啶-3-基)-4H-吡喃-3-甲腈反应的新型铜络合物 1,促进室温下的 CuAAC 反应,催化剂负载量低至 1 mol%,反应时间很短。
