The modified peptides contain groups suitable for post-assembly click reactions in water, namely azides and alkenes.

Substituted alkenes provided products that contain all carbon or nitrogen bearing quaternary centers in high yield.

Of the measured compounds, reactive alkenes and CO showed the strongest potential to form ground-level ozone.

The conversions of surface-bound alkyl groups to alkanes and alkenes are important steps in many heterogeneously catalyzed reactions.

We also report the experimental studies that extend the substrate scope of alkenes to ethyl vinyl ethers and thioethers.
