Abstract
Monophenylhydrazones involving both the phenacyl carbonyl group and the ring carbonyl group are formed as intermediates in the reaction of semicyclic 1, 5-diketones of the 2-(phenacylobenzyl) cyclohexanone type with phenylhydrazine in acid media. The former undergo subsequent conversion to the corresponding substituted indoles, whereas the latter are converted to substituted 1H-2, 3, 3a, 4-tetrahydropyrido [3, 2, l-j, k] carbazoles; in addition, the corresponding 5, 6, 7, 8-tetrahydroquinoline derivatives are also partially formed.
