Verbenone, a product of great interest for fine chemistry, was obtained as major product with yield up to 41% under optimized conditions. 2-hydroxy-3-pinanone was identified as a co-product of the reaction, but with very low amount (<7%). Kinetic investigations allowed determining the potential reaction intermediates and by-products. Moreover, mechanistic studies with radical scavengers confirmed that α-pinene oxidation mainly implies both carbon- and oxygen-centered radicals. © 2017 Elsevier B.V. %G English %2 https://univ-rennes.hal.science/hal-01671613/document %2 https://univ-rennes.hal.science/hal-01671613/file/Rauchdi%20et%20al.%20-%20Novel%20access%20to%20verbenone%20via%20ruthenium%20nanopartic.pdf %L hal-01671613 %U https://univ-rennes.hal.science/hal-01671613 %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ ENSC-RENNES %~ ISCR %~ SCR_OMC2012 %~ ISCR-OMC %~ STATS-UR1 %~ UR1-SPM %~ INC-CNRS %~ UR1-UFR-SPM %~ UR1-HAL %~ UR1-SDLM %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ CNANO-R %~ TEST-HALCNRS %~ UR1-MMS %~ TEST2-HALCNRS
