Ruthenium carbamoyl complexes: Coordination chemistry and CO release

Reaction of Ru(CO)4Br2 with a series of heterocyclic amines leads to a family of ruthenium carbamoyl complexes. These are analogous to the related ferracyclic systems reported by us as potential photoCORM systems (Chem. Commun., 2020, 56, 4300?4303). In contrast to the iron compounds, the ruthenium carbamoyls release CO only when irradiated in the UV, and show no activity as anti-inflammatory agents.

Automated summary

The reaction of Ru(CO)4Br2 with various heterocyclic amines leads to the formation of ruthenium carbamoyl complexes, which are similar to the ferracyclic systems reported by the researchers. Unlike the iron compounds, the ruthenium carbamoyls only release CO when irradiated with UV light, and they do not exhibit anti-inflammatory activity.
