Abstract Highly stereoselective and rapid (<1 min) addition reactions to the imine double bond of 2-(methylimino)acetate complexes [L(4)Co(O(2)CCH=NCH(3))](2+) [L(4) = (en)(2) (7), (tren) (11)] were achieved in aqueous solution with nitromethane, ethyl 3-oxobutanoate or diethyl malonate. The molecular structures of two product complexes, rac-(Δ*-R(C)*-S(N)*)-[Co(en)(2)(O(2)CCH[CH(2)NO(2)]NHCH(3))]ZnCl(4) and rac-(Δ*-R(C)*-S(N)*)-[Co(en)(2)(O(2)CCH[CH(2)COCH(3)]NHCH(3))]ZnCl(4), were established by X-ray diffraction.
