The catalytic activities of [RuClCp(PTA)2] (1) and [RuCp(PTA)2(H2O-κO)]OTf (2) were assessed for the redox isomerization of the cyclic allylic alcohol 2-cyclohexenol into cyclohexanone in water and biphasic media. Complex 2 showed unprecedented good TONs for the studied conversion both in water (TON = 647) and in the biphase of cyclohexene/H2O (TON = 3420) while 1 showed a lower but also good activity (water TON = 95, biphasic TON = 100). The catalytic reaction intermediate [RuCp(PTA)2(η2-C6H9OH)]CF3SO3 (3) was synthesized and characterized using NMR.
评估了[RuClCp(PTA)2]（1）和[RuCp(PTA)2(H2O-κO)]OTf（2）在水相和两相介质中环状烯丙醇2-环己烯醇氧化异构化为环己酮的反应中的催化活性。配合物 2 在水相（TON = 647）和环己烯/H2O 的两相体系（TON = 3420）中对所研究的转化表现出前所未有的高TON 值，而 1 则表现出较低但仍良好的活性（水相 TON = 95，两相 TON = 100）。使用 NMR 合成并表征了催化反应中间体[RuCp(PTA)2(η2-C6H9OH)]CF3SO3（3）。
