Berseneva, V. S. published the artcileSynthesis and properties of [(thiocarbamoyl)methyl]pyridinium (isoquinolinium) ylides, Name: 1-(Cyanomethyl)pyridin-1-ium chloride, the publication is Khimiya Geterotsiklicheskikh Soedinenii (1989), 1639-43, database is CAplus.
Treating pyridinium or isoquinolinium ylides I (R = CN) with H2S in EtOH containing NaOEt gave ylides I (R = CSNH2). The isoquinoline derivatives were cyclized by 1-chloro-2,4-dinitrobenzene to give 32% imidazoloisoquinoline II. Addnl. obtained from I were 15 and 30% imidazolopyridine and isoquinolines III, resp.
Khimiya Geterotsiklicheskikh Soedinenii published new progress about 17281-59-3. 17281-59-3 belongs to pyridine-derivatives, auxiliary class Pyridine,Nitrile,Salt, name is 1-(Cyanomethyl)pyridin-1-ium chloride, and the molecular formula is C7H7ClN2, Name: 1-(Cyanomethyl)pyridin-1-ium chloride.
