Reaction of 2-quinolyl thiocyanate with C-nucleophiles
Iijima,Hiyoshi,Miyashita
, p. 1090 - 1093 (2007/10/02)
2-Quinolyl thiocyanate (2) was found to react with C-nucleophiles, i.e., phenylacetonitrile, p-chlorophenylacetonitrile, p-cyanophenylacetonitrile, p-methoxyphenylacetonitrile, ethyl cyanoacetate, and malononitrile, in two ways, depending on the nature of
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.

Reaction of halogenated pyridines, quinolines, pyrimidines, and pyrazines with potassiophenylacetonitrile (5) in liquid ammonia under near-uv irradiation affords secondary nitriles, which then undergo oxidative decyanation under phase-transfer catalytic conditions to afford aryl hetaryl ketones in excellent yields.
Photostimulated Reactions of 2-Bromopyridine and 2-Chloroquinoline with Nitrile-Stabilized Carbanions and Certain Other Nucleophiles

Potassiophenylacetonitrile (2) reacts with 2-bromopyridine (1) and 2-chloroquinoline (4) via the SRN1 mechanism when the reactants are exposed to near-UV light in liquid NH3.Potassioacetonitrile (6) reacts similarly with 1 and 4 upon photostimulation; however, the photo-SRN1 reaction with 1 is accompanied by SNAr2 amination which becomes the major reaction in the dark or in the presence of di-tert-butyl nitroxide.Substrate 4 undergoes competing SNAr2 amination with amide ion to form 2-aminoquinoline (10) and SN(ANRORC) reactions with both amide ion and carban ion 6 to form 3-methylquinazoline (11) and 2-methyl-3-cyanoquinoline (12), respectively.Formation of 12 becomes the major pathway in reactions between 4 and 6 carried out in the dark. 4-Picolylpotassium (14) reacts with 1, 4, and 4-bromopyridinium chloride (16) under photostimulation to form the appropriate dihetarylmethanes, along with the corresponding amino heterocycles.Amination of 1, 4, and 16 predominates when these reactions are carried out in the dark.Ammonium thiophenoxide (20) undergoes a slow photo-SRN1 reaction with 1 but fails to produce the expected 2-quinolyl phenyl sulfide with 4 after 2 h of irradiation.Potassium salts of acetylene, phenylacetylene, and phthalimide do not react with 1 or 4 after 2 h of exposure to near-UV light.
