= H, o-, m-, or p-Me, m- or p-Cl, m- or p-OMe, m-CF3, p-F, or p-Br), of better than 98% isotopic purity have been prepared by treatment of the appropriate aryltrimethylstannane, XC6H4·SnMe3, with O-deuterioacetic acid containing 10%(w/w) of deuterium oxide at 75°. The benzyl compound m-CF3·C6H4·-CH2D has been correspondingly prepared by treatment of the compound m-CF3·C6H4·CH2·SiMe3 with sodium deuterioxide
氘代苯XC 6 H 4 D(X = H,o-,m-或p -Me,m-或p -Cl,m-或p -OMe,m -CF 3,p -F或p -Br ),通过在75°C下用含10%(w / w)氘化氧的O-氘代乙酸处理适当的芳基三甲基锡烷XC 6 H 4 ·SnMe 3,制备出纯度高于98%的同位素。苄基化合物m -CF 3 ·C 6 H4 ·-CH 2 d已被相应地由治疗的化合物制备米-CF 3 ·C 6 H ^ 4 ·CH 2 ·森3与钠deuterioxide在Ò -deuteriomethanol。该方法应具有通用性。
