Efficient large-scale preparation of phenyl 3-pyridazinyl ketone
Heinisch,Langer
, p. 773 - 778 (1994)
A convenient approach to phenyl 3-pyridazinyl ketone 4 permitting economical large scale preparation is proposed. Commercially available 3,6-dichloropyridazine 1 serves as the starting material in the three-step process.
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
REACTION OF METHOXY-N-HETEROAROMATICS WITH PHENYLACETONITRILE UNDER BASIC CONDITIONS
Yamanaka, Hiroshi,Ohba, Setsuya
, p. 895 - 909 (2007/10/02)
The monomethoxyl derivatives of various ?-electron deficient N-heteroaromatics reacted with phenylacetonitrile in tetrahydrofuran in the presence of sodium hydride to give α-phenyl-N-heteroareneacetonitriles in the yields ranging from 45 to 78percent.On the contrary, the reaction of these methoxyl derivatives with ethyl cyanoacetate or malononitrile under similar conditions was restricted within narrow limits.The synthesis of benzoyl-N-heteroaromatics by the air-oxidation of α-phenyl-N-hetroareneacetonitriles was described additionally.
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
