The syntheses of rhodium, iridium, and iron π complexes bearing 4,5-benzotropone ligands are reported. X-ray crystallog. analyses revealed that a tropone core coordinates to a metal center in a η4 manner with a tub-form geometry. Some of the benzotropone π complexes exhibited catalytic activity for N-alkylation of aniline by borrowing hydrogen. In the experiment, the researchers used many compounds, for example, Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1Electric Literature of C8H16Cl2Ir2).
Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Electric Literature of C8H16Cl2Ir2
