Abstract
Lanthanoid tri-2-propoxides ([Ln(OPr(i))3]n Ln=La, Nd, Gd, Yb) are act ive catalysts for the interchange reaction of the alkoxyl groups betwe en two kinds of esters. The La catalyst is the most active among them, and the activity is higher in nonpolar solvents than in polar ones. T he La catalyst is applicable to the ring-opening polymerization of 6-h exanolide.
