, p. 885 - 888 (2007/10/02)
Azidopyrazines bearing amino, methoxy and/or phenylgroups have been synthesized by reaction of pyrazine N-oxides with trimethylsilyl azide in the presence of diethylcarbamoyl chloride in refluxing acetonitrile.In most cases, the azidation occurs only at t

, p. 785 - 792 (2007/10/02)
By the coupling reaction of monochloropyrazines, dichloropyrazines, 2-chloropyrazine 1-oxides, and 2-chloropyrazine 4-oxides with tetraphenyltin, the corresponding phenylpyrazines were prepared in satisfactory yields.

, p. 311 - 320 (2007/10/02)
The monoxides of 2,6-dimethyl- (1), 2,6-diphenyl- (2), and 2-methyl-6-phenylpyrazines (3) were subjected to the reactions with phosphoryl chloride and acetic anhydride.Some reactions of the chloropyrazines and hydroxypyrazines obtained thus were also inve
