The reaction of tropone and potassium hydroxide in the presence of potassium ferricyanide gave tropolone, salicylaldehyde, and p-hydroxybenzaldehyde, while in the presence of the copper ammine complex it afforded 2-aminotropone and salicylonitrile. Similarly, when tropone was reacted with aqueous ammonia, methylamine, or dimethylamine, 2-aminotropone and its N-methyl derivatives were formed. The reaction of 2-phenyltropone with ammonia and methylamine, and the reaction of 2-α-naphthyltropone and 4-bromo-2-phenyltropone with methylamine in the presence of copper salt, also afforded 2-aminotropone derivatives and/or salicylaldehyde derivatives.
在铁氰化钾存在下,托品酮与氢氧化钾反应生成托品酮、水杨醛和对羟基苯甲醛,而在铜胺络合物存在下,则生成 2-氨基托品酮和水杨腈。同样,当托品酮与氨水、甲胺或二甲胺反应时,会生成 2-氨基托品及其 N-甲基衍生物。在铜盐存在的情况下,2-苯基丙酮与氨和甲胺反应,2-α-萘基丙酮和 4-溴-2-苯基丙酮与甲胺反应,也会生成 2-氨基托品衍生物和/或水杨醛衍生物。
