BIMETAL SALEN CATALYST USEFULLY APPLIED TO OPTICAL DIVISION OF RACEMIC EPOXIDE

PURPOSE: A bimetal salen catalyst is provided to show high catalyst activation and stereoselectivity, to be manufactured simply and economically and to extend range of nucleophile. CONSTITUTION: A bimetal salen catalyst or a solvate thereof has composition and structure expressed as a chemical formula 1 of Sal(M^1)M^2(X)n. In the chemical formula 1; Sal is a chiral salen ligand; M^1 and M^2 are transition metal ion independently coordinated in a salen ligand; X is a negative ion uniting with M^2 and forms the salt; n has value corresponding to an oxidation number of the transition metal ion M^2; a transition metal ion M1 is arranged at a center of the salen ligand; a transition metal ion M^2 is coordinated in two oxygen atoms of the salen ligand. The transition metal ion M1 is a metallic ion selected from a group consisting of cobalt(Co), manganese(Mn), chrome(Cr), vanadium(V), iron(Fe), molybdenum(Mo), tungsten(W), ruthenium(Ru) and nickel(Ni). © KIPO 2009 ...
