Page/Page column sheet 4; 5, (2008/06/13)
The present invention provides a method for transesterifying an ester, comprising combining the ester, a C1-C3 alcohol, and a heterogeneous catalyst of formula (I) or formula (II): wherein R′, R″ and R′″ are each H, (C1-C8)alkyl, (C6-C9)aryl, or (alk)3Si, wherein each alk is (C1-C4)alkyl; L is an organic linking moiety and X is a solid support material, and the salts thereof under conditions wherein the catalyst catalyzes the formation of the (C1-C3) ester of the acid portion of the ester and the corresponding free alcohol of the ester.
