The reactions of the isomeric thujan-3-ols with fluorosulphuric acid to give the 2,3-dimethyl-4-isopropylcyclopentenium ion have been investigated. The initial ring opening involves at least two mechanisms yielding a carbocation and an olefin. Subsequent reaction, possibly by elimination and olefin shift, gives the 2,3-dimethyl-4-isopropylcyclopent-2-enol, which rapidly ionises to the observed ion
已经研究了异硫氰酸-3-醇与氟硫酸的反应生成2,3-二甲基-4-异丙基环戊烯离子。初始开环涉及至少两个产生碳阳离子和烯烃的机理。随后的反应(可能通过消除和烯烃转移)得到2,3-二甲基-4-异丙基环戊-2-烯醇,后者迅速电离成所观察到的离子。已经通过氘示踪剂,在溶剂中和在底物中的反应研究了反应,并且通过将反应与相关底物的反应进行了比较。
