- W2078542261 abstract "The reactions of three 1-tropylazulenes—ethyl 2-acetamido-3-(cycloheptatrien-7-yl)azulen-1-carboxylate (I), 2-chloro-1-(cycloheptatrien-7-yl)azulene (II) and ethyl 3-(cycloheptatrien-7-yl)-azulen-1-carboxylate (III)—with phosphorus pentachloride were investigated. The reactions of I and II gave ethyl 2-acetamidoazulen-1-carboxylate and 1,2,3-trichloroazulene respectively. On the other hand, III afforded ethyl 3-chloroazulen-1-carboxylate (IV) and (3-ethoxycarbonylazulen-1-yl)tropylium perchlorate (V). The thermal isomerization of III formed ca. 2:3 mixtures of ethyl 3-(cycloheptatrien-3-yl)azulen-1-carboxylate (IV) and ethyl 3-(cycloheptatrien-1-yl)azulen-1-carboxylate (VII), but not ethyl 3-(cycloheptatrien-2-yl)azulen-1-carboxylate. The treatment of the above mixtures with phosphorus pentachloride raised the yield of V; however, IV was also obtained. The sodium borohydride reduction of V gave ca. 2:3 mixtures of VI and VII." @default.
