Reissert compound studies: the first pyridine reissert compound
Abstract
Treatment of pyridine with trimethylsilyl cyanide, benzoyl chloride, and aluminium chloride in methylene chloride gave 1-benzoly-2-cyano-1,2-dihydropyridine, providing the first example of a pyridine Reissert compound; several 3-substituted pyridines have also been converted to Reissert compounds.
