The η6-iridathiabenzene ring coordinated to CpFe+ in [η6-Cp*Ir(C,S-2,5-Me2T)]FeCp+ (2) undergoes attack by nucleophiles. Phosphorus-donors, CN-Bun, and CN- add to the Ir to give products with an η5- coordinated iridathiabenzene ligand. Hydride (Et3BH-, HFe(CO)4-) and Ph- nucleophiles attack at the sulfur to give products with Ir-SH and Ir-SPh groups and an iridacyclopentadiene unit. Other reactions of 2 are described together with structure determinations of key compounds.
