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-benzylpyridazine (17) and 3-benzoylpyridazine (11) has been observed. Key Words: 3-Pyridazinylmethyl chlorides, reactions with O-nucleophiles / Telesubstitution / Dismutation, thermally induced
