3-aryl-4, 5-pentamethylene-l, 2, 4-triazoles, α-halogeno ketones, 2a, 8a-triazacyclopenta[c, d]azulene, correlation dependence of proton chemical shifts, cyclization in alkaline media, quaternary phenacylium saltsAbstract
Derivatives of the previously unknown heterocyclic system 2,2a,8a-triazacyclopenta[c,d]azulene were synthesized by condensation of 3-aryl-4,5-pentamethylene-1,2,4-triazoles or 2-(β-aroylhydrazin)-1-aza-Δ-cycloheptene with α-halogeno ketones, followed by cyclization of the intermediate products in alkaline media.
