The water-soluble copper complex generated in situ from CuCl2 and 2,2′-biquinoline-4,4′-dicarboxylic acid dipotassium salt (BQC), has been revealed as a highly efficient and selective catalyst for the oxidation of secondary 1-heteroaryl alcohols to the corresponding heteroaromatic ketones with aqueous tert-butyl hydroperoxide, under mild conditions. The catalytic system is compatible with different
由CuCl 2和2,2'-联喹啉-4,4'-二羧酸二钾盐(BQC)原位生成的水溶性铜络合物已被证明是一种高效且选择性的催化剂,可氧化次要1-在温和条件下,用叔丁基过氧化氢水溶液将杂芳基醇转变为相应的杂芳族酮。该催化体系与不同的杂环兼容,例如吡啶,吡咯,吲哚,噻吩,呋喃,噻唑和咪唑。
