摘要

Abstract Reactions of 3-α-chlorobenzylpyridazine (4) with alkoxides have been found to yield 6-substituted or 4-substituted 3-benzylpyridazines (7a–c, 8a–c) rather than the usual ethers (6a–c). Introduction of an electron-donating substituent into the 6-position of the pyridazine nucleus of 4 has been shown to suppress such telesubstitution processes. With phenyl-3-pyridazinylmethanol (3), thermally induced dismutation affording 3- ...
