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.

Exchange Reactions

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.
