Photocatalytic reaction creates cyclopropanes from unactivated alkenes The oxygen-mediated redox pathway makes carbon triangles without relying on hazardous reagents ...

Organic peroxy radicals (RO 2) and Criegee intermediates (CI, carbonyl oxides) are key reactive species in atmospheric chemistry and play crucial roles in the formation of secondary organic ...

Methyl peroxy, a key radical in tropospheric chemistry, was recently shown to react with the hydroxyl radical at an unexpectedly high rate. Here, the molecular reaction mechanisms are elucidated ...
