Spin-state engineering of cobalt(IV)-oxo enables direct oxygen atom transfer for high-efficiency olefin epoxidation (opens in new tab)

Proceedings of the National Academy of Sciences, Volume 123, Issue 24, June 2026. SignificanceOxygen atom transfer (OAT) is crucial in synthesis, yet balancing activity and selectivity remains challenging. Notably, high-valent cobalt-oxo species (CoIV=O), are principal reactive species in OAT. However, their typical square-pyramidal ...
