摘要：

Lanthanoid tri-2-propoxides ([Ln(OPr(i))3]n Ln=La, Nd, Gd, Yb) are active catalysts for the interchange reaction of the alkoxyl groups between 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. The La catalyst is applicable to the ring-opening polymerization of 6-hexanolide.
