Kinetics and Thermodynamics of Atmospherically Relevant Aqueous Phase Reactions of α-Pinene Oxide

“…Some species were identified by comparison to commercially available standards: α-pinene oxide, trans -sobrerol ( trans - p -menth-6-ene-2,8-diol), p -cymene, and 2,3-pinanediol ((1 S ,2 S ,3 R ,5 S )-(+)-2,3-pinanediol and (1 R ,2 R ,3 S ,5 R )-(−)-2,3- pinanediol (all obtained from Sigma Aldrich)). However, several other noncommercially available reaction products were identified via previously reported 1 H and 13 C CDCl 3 NMR data: cis -sobrerol, trans -carveol, cis -carveol, , pinol, campholenic aldehyde, and fencholenic aldehyde…”

However, several other noncommercially available reaction products were identified via previously reported 1 H and 13 C CDCl 3 NMR data: cis-sobrerol, 19 trans-carveol, 20 cis-carveol, 21,22 pinol, 23 campholenic aldehyde, 20 and fencholenic aldehyde. 24 The relative amounts of reaction products were calculated by peak integration of unique nuclei for each species, referenced to the 9 methyl protons at 0.00 ppm from DSS, the 6 protons at 7.34 ppm from benzene, or the 6 carbon atoms at 128.4 ppm from benzene.…”
