The inactive chiral (salen)Cocomplex is easily activated by InCl3 and TlCl3 Lewis acids by forming heterometallic salencomplexes. These complexes show very high catalytic activity for the synthesis of enantiomerically enriched terminal epoxides (>99% ee) and 1,2‐diols simultaneously via hydrolytickineticresolution. Strong synergistic effects of different Lewis acids, Co‐In and Co‐Tl, were exhibited
