Electric Literature of 135034-10-5, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.135034-10-5, Name is 3-Chloro-6-iodopyridazine, molecular formula is C4H2ClIN2. In a Article，once mentioned of 135034-10-5

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 1b and 4b underwent palladium catalysed Suzuki, Sonogashira and other coupling reactions.
