Half-sandwich η5-pyrrolyl rhodium(i) complexes with alkene coordination: synthesis and reactivity exploration

Abstract

Rhodium alkene complexes with η⁵-pyrrolyl ligands are successfully synthesized and fully characterized by X-ray analyses and NMR spectroscopy. The dynamics of pyrrolyl and alkene coordination as well as the combined σ- and π-ligation ability of pyrrolyl are demonstrated in the reactions of these half-sandwich complexes with isocyanide, organic azide and Lewis acid.
