exo-stericとは 意味・読み方・使い方

To provide a method for producing a norbornene derivative, by which a specific norbornene derivative (exo isomer) in which the steric configuration of a substituent is exo configuration can be produced in good selectivity and in a sufficiently high yield, even when the kind of a halogen atom in a raw material compound used on the introduction of the substituent such as phenyl group is bromine atom, chlorine atom or the like.例文帳に追加

フェニル基等の置換基を導入する際に用いる原料化合物中のハロゲン原子の種類が臭素原子や塩素原子等であっても、置換基の立体配置がｅｘｏ配置となる特定のノルボルネン誘導体（ｅｘｏ体）を選択性よく且つ十分に高い収率で製造することが可能なノルボルネン誘導体の製造方法を提供すること。 - 特許庁

This method for producing the norbornene derivative of reaction formula (III) is characterized by reacting a norbornadiene derivative with a phenyl halogen compound in the presence of a palladium catalyst in which a phosphine-based ligand is arranged on a divalent palladium, a solvent such as N,N-dimethylformamide, and a reducing agent to obtain the norbornene derivative whose steric configuration is exo configuration.例文帳に追加

ホスフィン系配位子が２価のパラジウムに配位したパラジウム触媒と、Ｎ，Ｎ−ジメチルホルムアミド等の溶媒と、還元剤との存在下において、ノルボルナジエン誘導体とフェニルハロゲン化合物とを反応せしめ、立体配置がｅｘｏ配位であるノルボルネン誘導体を得ることを特徴とするノルボルネン誘導体の製造方法。 - 特許庁
