Abstract: Treatment of the lithium salt of beta-ketimine with FeCl2(THF)(1.5) in the presence of LiN(SiMe3)(2) and water affords the multimetallic iron(II)-lithium complex 1, [(L-Me)(2)Fe](3)Li2O [ where L-Me = MeC(O) CHC(NMe)Me]. In complex 1 three separated (L-Me)(2)Fe units are bound together by one Li2O species, which leads to the formation of an interesting {Fe3Li2O} core structure. Complex 1 can be used as a single-component initiator for the ring-opening polymerization of e-caprolactone at room temperature, achieving a monomer conversion of 98% within 100 min, and a narrow molecular weight distribution (PDI = 1.28) of the resulting polymer.
