摘要
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 heterocycles such as pyridines, pyrroles, indoles, thiophens, furans, thiazoles, and imidazoles. (c) 2006 Elsevier Ltd. All rights reserved.
