Unexpected high yield of acrolein underlies the importance of the hydrogen-abstraction mechanism in photooxidation of allyl methyl sulfide (AMS).
Cardona AL, Teruel M, Ventura ON. Cardona AL, et al. Chemosphere. 2024 Apr;354:141693. doi: 10.1016/j.chemosphere.2024.141693. Epub 2024 Mar 18. Chemosphere. 2024. PMID: 38508461
This work explores theoretically the gas phase oxidation of allyl methyl sulfide (AMS, H(2)CCHCH(2)SCH(3)) initiated by ()OH radicals, focusing on the H-abstraction pathway at the M06-2X-D3/aug-cc-pVTZ and MN15/aug-cc-pVTZ levels of theory (m06Tz and mn15Tz). ...The compar …
