Article Abstract
The first examples of heterogeneous Fe-catalysed cyclopropanation reactions are presented. Pyrolysis of -generated iron/phenanthroline complexes in the presence of a carbonaceous material leads to specific supported nanosized iron particles, which are effective catalysts for carbene transfer reactions. Using olefins as substrates, cyclopropanes are obtained in high yields and moderate diastereoselectivities. The developed protocol is scalable and the activity of the recycled catalyst after deactivation can be effectively restored using an oxidative reactivation protocol under mild conditions.

Article Synopsis
- The study developed a micron zero-valent iron/N-doped graphene-like biochar (mZVI/NGB) composite for effective degradation of tetracycline (TC) through oxygen activation.
- The composite showed nearly 100% TC removal efficiency at a circumneutral pH and was resilient against several co-existing anions.
- The degradation primarily occurred via a non-radical pathway involving oxygen and electron transfer, with the Fe/Fe redox cycle enhancing the composite's catalytic activity, contributing to sustainable water treatment solutions.
