Nitrogen Phosphorus

The substitution of the labile carbonyl groups of the rhenium–quinone radical complexes by nitrogen, phosphorus, arsenic, antimony, and oxygen donor ligands was observed. The extent of substitution was evidenced from esr spectra, while the configuration of the ligands about the rhenium centre was deduced from infrared absorption spectra. Rate data was obtained for the mono-substitution reaction which can be best interpreted in terms of concurrent major dissociative (D) and minor dissociative interchange (Id) pathways. The relative thermodynamic stability of a number of substituted rhenium–quinone radical complexes was also investigated by competitive ligand exchange reactions.

Insight Into

This study examined the solution-phase exchange reactions of triphenylphosphine (PPh3) ligands on Au8L72+ (L = PPh3) gold clusters with three different tolyl ligands using electrospray ionization mass spectrometry to provide insight into how steric differences in the phosphines influence the extent of ligand exchange and the stability of the resulting mixed-phosphine clusters.

Abstract Ligand exchange reactions of molybdenum hexacarbonyl with tridentate diacidic ligands were studied by means of photochemical and thermal activation. The reaction products were characterized by mass spectrometry. Species such as MoL2, MoH2L2 and MoO2L could be identified.
