Description

【発明が解決しようとする課題】
上記の方法(1)では、反応系で生成する過ギ酸などの過酸は爆発性が高く取扱いが危険であり、エポキシ体が反応系内に存在するカルボン酸と反応することによりエステル体等が生成してしまい、目的とするエポキシ体の選択率が低下する。方法(2)では、高価な貴金属触媒を使用しており、また加水分解反応が進行してエポキシ化選択率は低い。方法(3)では、基質特異性が激しく、親水性の低いオレフィンではエポキシ化選択率は低い。[0004]
[Problems to be solved by the invention]
In the above method (1), the peracid such as formic acid generated in the reaction system is highly explosive and handling is dangerous, and the ester forms by reacting with the carboxylic acid present in the reaction system. It forms, and the selectivity of the target epoxy body falls. In the method (2), an expensive noble metal catalyst is used, and the hydrolysis reaction proceeds and the epoxidation selectivity is low. In the method (3), the substrate specificity is high, and the low hydrophilicity olefin has low epoxidation selectivity.
