Manganese Asymmetric Catalysis: From Mn-Salen Epoxidation to Base-Metal Pincer Catalysts

Manganese occupies a unique position in asymmetric catalysis: it is both the metal of the classic Jacobsen epoxidation catalyst (since 1990) and a leading base-metal candidate in …

Iron and Cobalt Base-Metal Asymmetric Catalysis: Sustainable Alternatives to Precious Metals

The drive to replace scarce, expensive precious metals (Ru, Rh, Ir, Pd) with earth-abundant base metals (Fe, Co, Mn, Ni, Cu) is reshaping asymmetric catalysis. Iron and cobalt, the …

Jacobsen Mn-Salen Catalysts for Asymmetric Epoxidation of Unfunctionalized Olefins

Eric Jacobsen’s Mn(III)-salen complex, introduced in 1990, solved a long-standing problem: the enantioselective epoxidation of unfunctionalized olefins. Unlike the Sharpless …
