Abstract:
In the present work, we have investigated the bimolecular reactions of biogenic (methyl vinyl ketone oxide (MVK-OO) and methacrolein oxide (MACR-OO)) and anthropogenic (acetaldehyde oxide (CH3CHOO)) Criegee intermediates with nitrous acid (HONO) using quantum chemical calculations and kinetic modelling. For quantum chemical calculations, we used the CCSD(T)/CBS//M06-2X/aug-cc-pVTZ level of theory, while for the rate constant calculation, we carried out Rice-Ramsperger-Kassel-Marcus theory/master equation kinetics calculations. Our study suggests that HONO can serve as a major bimolecular sink for MVK-OO, whereas it acts as a minor sink for MACR-OO, becoming significant only under low-humidity and low-temperature conditions. For CH3CHOO, HONO acts as the most dominant sink (relative to H2O and (H2O)2) after unimolecular decay. Overall, the findings suggest that HONO can act as a potential sink for Criegee intermediates in both biogenic (forested) and anthropogenic (urban) environments.

Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...
