Telesubstitution and Dismutation Reactions in the Series of Phenyl-3-pyridazinylmethane Derivatives
Heinisch, Gottfried,Huber, Thierry
, p. 19 - 22 (2007/10/02)
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
Preparation of Heteroaryl Phenylmethanes and a 13C and 15N NMR Spectroscopic Study of their Conjugate Carbanions. Rotational Isomerism and Charge Maps of the Anions and Ranking of the Charge Demands of the Heterocycles

2-Benzylpyridazine, 4-benzylpyrimidine, 2-benzylpyrimidine and 2-benzylpyrazine, (5-8) have been prepared in order to study their 13C and 15N spectra and those of their conjugate carbanions (1-4).These systems are aza-homologues of the previously reported
Pyridazines. L . Syntheses and Reactions of Phenyl(3-pyridazinyl)methane Derivatives
Heinisch, Gottfried,Huber, Thierry
, p. 1787 - 1791 (2007/10/02)
A convenient approach to phenyl(3-pyridazinyl)ketone (6) and phenyl(3-pyridazinyl)methanol (7) is proposed.Reactions of the related diarylmethyl chloride 8 with various N- and S-nucleophiles were found to afford the expected amines 9a-c, 10a-c and thioeth
