  摘要：

  3,6-Dichloropyridizine 1a was converted in good;yield into its mono-iodo derivative 1b when treated with a mixture of hydriodic acid and sodium iodide. Pure samples of the mono-iodo derivatives 2b, 3b and 4b could not be obtained from their corresponding dichlorinated precursors with these reagents. Compounds Ib and 4b underwent palladium catalysed Suzuki, Sonogashira and other coupling reactions. (C) 1999 Elsevier Science Ltd. All rights reserved.

  日期：2005.2

  Pd-catalyzed cross-coupling reactions of 3,6-dichloropyridazine (1) with benzyl, aryl, and alkyl organozinc compounds led to selective mono-substitution of one of the chlorine atoms. The subsequent cross-coupling of the resulting monochlorides with RZnCl afforded unsymmetrical 3,6-carbon-disubstituted pyridazines.

  Pd催化的3,6-二氯哒嗪（1）与苄基，芳基和烷基有机锌化合物的交叉偶联反应导致氯原子之一的选择性单取代。随后将所得的一氯化物与RZnCl交叉偶联，得到不对称的3,6-碳二取代的哒嗪。
