| Outline of Final Research Achievements |
In this study, we found that the reactivity of N-bromosuccinimide, whose reactivity was conventionally low, is greatly improved by using phenylthiotrimethylsilane, a sulfur compound, with N-bromosuccinimide.
(1) Bromination and chlorination of relatively electron poor aromatic rings, which cannot proceed with N-bromosuccinimide alone, are efficiently promoted by the addition of phenylthiotrimethylsilane. (2) We found that direct esterification from cyclic acetals proceeded by using these reagents combination. (3) By using this reagent combination, we found that radical reactions proceed at room temperature.

| Academic Significance and Societal Importance of the Research Achievements |
臭素や塩素といったハロゲン化合物は様々な分野で有用な化合物として用いられており、その合成法も多く開発されています。しかし、反応性の高い反応剤は様々な化合物をハロゲン化することができますが、反面、取り扱いがむずかしいといった問題があります。今回開発した方法は、反応性は低いものの取り扱いが容易な試薬に対して、硫黄化合物を添加することでその反応性を大きく向上させることに成功しました。
