Azabenzocycloheptenones. Part VIII. Further observations in the dibenz[b,d]azepin-7-one field
Abstract
A compound formerly believed to be a monomeric dibenzazatropone is shown to be a dimer and to yield a bisazatropone on oxidation. The monomeric dibenzazatropone, 6-ethoxy-7-oxodibenz[b,d]azepine, has been prepared. Syntheses and reactions of further N-toluene-p-sulphonyl 6-substituted dibenz[b,d]azepinones with bases have been studied.
