Two heterobimetallic complexes, [(TBBP) 2 Zn][(Na) 2 (THF) 4 ] ( 3 ) and [(TBBP) 2 Zn][(Li) 2 (THF) 4 ] ( 4 ) can initiate the ring‐opening polymerization of L ‐lactide in a controlled fashion. Complex 3 can initiate the ring‐opening polymerization of unsublimed L ‐lactide under moist conditions even in the presence of H 2 O, to yield a high conversion and with controllable molecular weight.
