Abstract

(7) Another CCN system where-C= C- is the part of benzene and thus the heterocycle formed is indazole was reported while our investi-gation was under way. See: Vivona, N.; Cusmano, G.; Macaluso, G.; Frenna, V.; Ruccia, MJ Heterocycl. Chem. 1979, 16, 783.(8) It is interesting to note that even the oxadiazole with a saturated CHzCHzNHR side chain instead of-C= CN- undergoes the rear-rangement reaction to give a nonaromatic ...
