and 1,4-butanediol, has been characterized via single-crystal X-ray
diffraction, revealing a unique supramolecular structure. Its
functionality as a highly active initiator for the ring-opening
polymerization of cyclic esters is demonstrated. A discrete titanium
trimer containing the related ligand (2R,3R)-2,3-butanediol has also
been prepared, and it shows analogous activity as a polymerization
initiator.
