Reactions of 4-cyano-3(2,H)-pyridazinone (1) and tetrazolo[1,5-b]pyridazine-8-carbonitrile (4) with phenylmagnesium chloride were found to be governed by formal replacement of the nitrile function to afford the phenyl-substituted pyridazine derivatives 3 and 5 rather than the expected aryl heteroaryl ketones.
发现4-氰基-3(2,H)-哒嗪酮(1)和四唑并[1,5 - b ]哒嗪-8-腈(4)与苯基氯化镁的反应是由腈官能团的正式取代控制的。得到苯基取代的哒嗪衍生物3和5,而不是预期的芳基杂芳基酮。
