Applications of η5-cyclopentadienyl molybdenum complexes as catalysts for achiral and chiral epoxidation of olefins are reviewed. The discussion is categorized according to the different complex types which arise from the variety of ancillary ligands coordinated to the (η5-C5R5)Mo moiety. The yields and turnover frequencies (TOFs) achieved under standard conditions with these different catalysts have been considered and thus, an assessment of the dependence of catalytic activity on the ligand environment is presented.
Keywords: Catalysis, cyclopentadiene, epoxidation, homogeneous, molybdenum, olefin, turnover frequencies (TOFs), haptotropic shifts, Cp moiety, nucleophilic olefin, cyclopentadienyl moiety, Liquid-phase catalytic epoxidation, FTIR spectroscopic, Ansa-Bridged Complexes, Binuclear complexes
