nitrile (11) from 6-chloroquinoline, l-benzoyl-6-methyl-l, 2-dihydroquinaldonitrile (111) from 6- methylquinoline and 2-benzoyl-3-methyl-1, 2-dihy-droisoquinaldonitrile (IV) from 3- methylisoquinoline. When 6-nitroquinoline, 8-nitroquinoline or@-carboline was used no Reissert compound was obtained; the original base was recovered, and an oil, presumed to be phenylglyoxylonitrile dimer, was isolated. Even with these additional examples, other ...
