Criegee intermediates are transient carbonyl oxide species generated during the ozonolysis of alkenes, and they play a pivotal role in atmospheric oxidation processes. Their formation initiates a ...

Reactions that completely break carbon-carbon double bonds have particular transformative power in synthesis. Ozonolysis, which splits one alkene into two carbonyl compounds using trioxygen, is widely ...

Researchers have identified a surprising phenomenon: severe winter ozone (O₃) pollution in Lanzhou, China, primarily caused by alkene emissions from local petrochemical industries. Typically linked to ...

Ozone pollution isn’t just a summer story anymore. In parts of northern China, high ozone levels are now appearing during winter—an alarming twist that defies decades of air quality science. This ...
