| Abstract: | The zinc dichlorido and zinc diacetato complexes of the chiral tricyclic 9-oxabispidine (1R,2S,9S)-11-methyl-13-oxa-7,11-diazatricyclo 7.3.1.02,7] tridecane were prepared and characterized by X-ray crystallography. The latter complex was found to catalyze the solvent-free polymerization of d,l-lactide to give polylactide. |
