• The catalytic activities of [RuClCp(PTA) 2 ] ( 1 ) and [RuCp(PTA) 2 (H 2 O-κ O )]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/H 2 O (TON = 3420) while 1 showed a lower but also good activity (water TON = 95, biphasic TON = 100). The catalytic reaction intermediate [RuCp(PTA) 2 (η 2 -C 6 H 9 OH)]CF 3 SO 3 ( 3 ) was synthesized and characterized using NMR. The catalytic isomerization of 2-cyclohexenol to cyclohexanone has been accomplished with large conversion rates using two Ru( ii ) catalysts containing PTA under mild reaction conditions in both water and biphasic media.
