On the reaction of N-arylnitrilium salts with acetylenes: Synthesis of substituted quinolines

Article abstract of DOI:10.1055/s-1992-26250

Quinolinium salts 3 are obtained from the reaction of N-arylnitrilium salts 1 with acetylenes 2. With aqueous base the salts 3 are transformed into the corresponding quinolines 4.
