Article abstract of DOI:10.1039/DT9930001031

Fluoroacyl complexes of iridium have been prepared by reaction of XeF2 with the iridium carbonyl complexes + (L = PMe3, PMe2Ph, PEt2Ph or PEtPh2). and +.The reaction can be viewed as an unusual type of oxidative addition and this is supported by the need for strongly electron-donating phosphines for reaction to occur.The complex + reacts with SiH3X (X = CN, NCS or NCO) to give acyl complexes + and with BF3 to give 2+.This dication reacts further with PMe3 to give an acyl product with PMe3 bound to a carbonyl ligand.The complex + reacts with XeF2 + BF3 to give 2+.Products were characterised using 19F, 31P and 13C NMR spectroscopy.
