摘要

Stable tris-, bis-and mono [9-(azuleno [1, 2-b] thienyl)] methyl cations (7a, 8a and 9a) and their derivatives, with a 6-isopropyl substituent on each azuleno [1, 2-b] thiophene ring (7b, 8b and 9b) were prepared by the hydride abstraction reaction of the corresponding methane derivatives. The bonding situation of these compounds including the methane derivatives was examined by analysis of the 3J (H, H) values for the seven-membered ring from the ...
