Inorganic solids have pronounced effects on the product distribution from decomposition of the title compounds; zeolite Kβ is particularly useful for directing the synthesis of indolinones such as 5-methoxy-N-methylindolin-2-one, which is formed in 89% yield from 2-diazo-2-methoxycarbonyl-N-(4-methoxyphenyl)-N-methylethanamide; speculation is made about a possible mechanism.
无机固体对标题化合物分解产物的分布有明显的影响;沸石 Kβ 对指导吲哚啉酮类化合物的合成特别有用,如 5-甲氧基-N-甲基吲哚啉-2-酮,它是由 2-重氮-2-甲氧基羰基-N-(4-甲氧基苯基)-N-甲基乙酰胺生成的,产率为 89%;对其可能的机理进行了推测。
