The synthesis of a series of 18-electron chiral-at-metal (cycloheptatrienyl)molybdenum complexes [(eta(7)-C7H7)Mo(prophos)X] [prophos = (R)-1,2-bis(diphenylphosphanyl)propane; X = NCMeBF4, Cl, I, CN, H, Me] is reported, which consist of diastereomers differing only in the metal configuration. Diastereomer enrichments have been achieved and the configurational stability of the compounds [(eta(7)-C7H7)Mo(pro-phos)X] has been studied and compared with the isoelectronic ruthenium complexes [(eta(5)-C5H5)Ru(prophos)X]. The stereochemistry of the substitution reactions has been investigated, and X-ray analysis and NMR spectroscopy were used to determine the absolute configuration of the complexes.
