[RuCl2(η6-arene)(R)-PR(binaphthoxy)}] (arene = benzene (1), p-cymene (2), mesitylene (3); R = Ph (a), OPh (b), piperidyl (c)) are described. Derivatives 1–3 have been employed to promote the kinetic resolution of allylic alcohols through a redox-isomerization process. As a general trend, the best selectivities are attained with the more sterically hindered catalysts i.e. those containing p-cymene or mesitylene ligands
手性芳烃的合成与表征钌 配合物[的RuCl 2(η 6 -arene)([R)-PR(binaphthoxy)}](芳烃= 苯(1),对苯甲基(2),均三甲苯(3); R = Ph(a),OPh(b),哌啶基(c))被描述。衍生物1-3已被用于通过氧化还原异构化过程促进烯丙基醇的动力学拆分。一般趋势是,受空间位阻更大的催化剂(即含有对苯甲基 或者 均三甲苯 配体。
