A solution of 4-chloroquinoline 1-oxide (1) and α-phenylpropionitrile in benzene was treated with 50% sodium hydroxide and a catalytic amount of tetrabutyl-ammonium bromide at 50° for 8 hr with vigorous stirring to produce 4-(α-cyano-α-phenyl)ethylquinoline 1-oxide in 72% yield. Reactions of 1 with butyl vinyl ether adducts of some aromatic aldehyde cyanohydrins under the same conditions gave, after hydrolysis with hot 10% hydrochloric acid, 4-aroylquinoline 1-oxides.
