(R,R)-N,N'-Bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediaminocobalt(II) is a cobalt(II) salen complex commonly referred to as a Jacobsen-type catalyst, widely employed in C–H activation reactions and asymmetric catalysis. This chiral catalyst facilitates direct functionalization of unactivated carbon–hydrogen bonds and is also effective in enantioselective epoxidation and epoxide ring-opening reactions. It is a valuable reagent for synthetic organic chemistry laboratories working on pharmaceutical intermediates and fine chemical synthesis.
