Transesterification Catalyzed by Lanthanoid Tri-2-propoxides
TL;DR: In this article, the transesterification of esters with alcohols was efficiently catalyzed by Ln(OPri)3, and the catalytic activity decreased in the following order; La > Nd > Gd > Yb.

Indium-Catalyzed Reductive Esterification of a Carboxylic Acid: Sequential Preparation of an Ester and Symmetrical Ether
TL;DR: In this article, an unprecedented reductive dimerization of two carboxylic acids to produce ester derivatives by a combination catalyst involving InBr3 and sulfuric acid is described, and a sequential conversion of the in-situ formed ester to a symmetrical ether by indium-catalyzed deoxygenation of the ester with a hydrosilane in the same pot was also demonstrated.
