asymmetrical atomとは 意味・読み方・使い方

This method for carrying out an asymmetric coupling reaction between different two kinds of aromatic compounds comprises reacting an aromatic lead compound having lead atom bonded to an aromatic ring, with a metal phenoxide compound in the presence of a tertiary amine compound having a fixed conformation hardly causing the inversion of an unshared electron pair of the nitrogen atom to mutually form the bond between aromatic rings to provide the objective asymmetrical compound.例文帳に追加

２種の異なる芳香族化合物間での不斉カップリング反応方法であって、芳香環に鉛原子が結合している芳香族鉛化合物と金属フェノキシド化合物とを、立体配座が固定されて窒素原子の非共有電子対が反転しにくい３級アミン化合物の存在下に反応させ、芳香環相互の結合を形成して不斉化合物を生成させる。 - 特許庁
