It is found that they exist in the form of phenol and phenoxide in solution .The ratios of the two forms and spectral behavior change with th... 实验结果显示,它们在溶液中以酚式和酚氧负离子式共存,且其2种形式的相对含量随介质的不同而改变,其光谱也随之变化。
Substituted phenoxy acetophenone was synthesized by an one-pot reaction of acetophenone with polymer-supported bromine and substituted phenoxide. 探讨了聚合物支载的过溴离子及取代苯氧基离子于单锅中,以苯乙酮为底物,合成取代苯氧基苯乙酮的方法,并与分步合成法相比较。
Quaternary ammonium salt was used as catalyst for transporting phenoxide ion between two phases to give benzyl phenyl ether and its derivatives in multiphase system. 在多相体系中,以铵盐为催化剂合成苄苯醚及其衍生物,产率高达91%25,转化率达到983%25。
The method could be divided into “active phenoxide” routing and “active cyanogen” routing according to the actual monomer synthesis process, as well as each reaction mechanism is discussed. 根据实际的操作过程,将“卤化氰-酚法”划分为“活性酚氧离子”路线和“活性氰”路线,讨论了其可能的反应机理。
