Y is it so? Dimeric yttrium–salen complexes (see structure; N blue, O red, Y magenta) catalyze the highly enantioselective ring‐opening of meso ‐aziridines by TMSCN and TMSN 3 . To explain the dramatic differences in the selectivity between mono‐ and dimeric catalysts, a dimetallic mechanism based on the solid‐state structure of the dimer is proposed.
