摘要：

A wide variety of aldehydes are efficiently dimerized to esters by a catalytic amount of (C(5)Me(5))(2)LnCH(SiMe(3))(2) (Ln = Nd, La). The reaction is applicable to the synthesis of polyesters from dialdehydes. A stoichiometric reaction of the lanthanum complex with benzaldehyde indicates the intermediacy of alkoxo complexes in the catalysis.
