Pentafluorophenyl derivatives are expressed by the formula (I): ##STR1## where X represents an alkyl group having from 1 to 4 carbon atoms or a halogen atom; Y represents any group of --CH.sub.2 OH, --COOH, --COCl, --CON.sup.1 R.sup.2, or --OSO.sub.2 R.sup.3 ; R.sup.1, R.sup.2 and R.sup.3 represent an alkyl group which may have a substituted group, an aryl group which may have a substituted group, or a hydrogen atom except for R.sup.3. However, when X to a halogen atom, Y is the aforementioned groups other than --OSO.sub.2 R.sup.3. A racemate and/or an optical active form of the pentafluorophenyl derivatives can be used suitably as derivatizing agents for electron capture detection and optical resolution for analysis and as intermediates for medicines, agricultural chemicals, functional polymers, etc. The pentafluorophenyl derivatives are produced from pentafluorostyrene oxide.
Pentafluorophenyl衍
生物由以下公式(I)表示:##STR1##其中X代表具有1至4个碳原子的烷基基团或卤素原子;Y代表--CH.sub.2 OH,--COOH,--COCl,--CON.sup.1 R.sup.2或--OSO.sub.2 R.sup.3的任何基团;R.sup.1,R.sup.2和R.sup.3代表可能具有取代基团的烷基基团,可能具有取代基团的芳基基团,或氢原子,但R.sup.3除外。但是,当X为卤素原子时,Y是上述除--OSO.sub.2 R.sup.3之外的基团。Pentafluorophenyl衍
生物的外消旋体和/或光学活性形式可适当用作电子捕获检测和光学分辨分析的衍生剂,以及用作药品、农药、功能性聚合物等的中间体。Pentafluorophenyl衍
