Kinetic Analysis as an Optimization Tool for Catalytic Esterification with a Moisture-Tolerant Zirconium Complex
Dalla-Santa, Oscar,Lundberg, Helena,Szabó, Zoltán,Villo, Piret
, p. 6959 - 6969 (2020/06/27)
This work describes the use of kinetics as a tool for rational optimization of an esterification process with down to equimolar ratios of reagents using a recyclable commercially available zirconocene complex in catalytic amounts. In contrast to previously reported group IV metal-catalyzed esterification protocols, the work presented herein circumvents the use of water scavengers and perfluorooctane sulfonate (PFOS) ligands. Insights into the operating mechanism are presented.
A nucleophilic Fe catalyst for transesterifications under neutral conditions
Magens, Silja,Ertelt, Melanie,Jatsch, Anja,Plietker, Bernd
, p. 53 - 56 (2008/09/17)
Carboxylic esters belong to the most important functional groups in organic chemistry. Strong efforts have been made in developing mild catalytic procedures for their preparation. Among the various methods developed to date, transesterifications have occupied an important space. In the present paper, a new catalytic method for this process based on the use of nucleophilic Fe(-II) complexes is presented. Evidence for the formation of an intermediate acyl Fe complex will be presented as well as investigations on scope and limitations.
Ligand-induced acceleration of the intramolecular [3 + 2] cycloaddition between alkynes and alkylidenecyclopropanes
Duran, Juan,Gulias, Moises,Castedo, Luis,Mascarenas, Jose L.

(Chemical Equation Presented) Bulky phosphite L6 and several sterically robust phosphoramidites are excellent ligands for promoting the Pd-catalyzed [3 + 2] intramolecular cycloaddition between alkylidenecyclopropanes and alkynes. The use of th
