Nucleophilic addition to the η6-iridathiabenzene ligand in [η6-Cp*Ir(C,S-2,5-Me2T)]FeCp+
摘要:
The eta(6)-iridathiabenzene ring coordinated to CpFe+ in [eta(6)-Cp*Ir(C,S-2,5-Me2T)]FeCp+ (2) undergoes attack by nucleophiles. Phosphorus-donors, C N-Bu '', and CN- add to the Ir to give products with an eta(5)-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. (c) 2005 Elsevier B.V. All rights reserved.
