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.
这项工作描述了动力学作为一种工具,用于合理优化酯化过程,该过程使用催化量的可回收市售锆茂络合物,试剂比例低至等摩尔比。与先前报道的第IV族金属催化的酯化方案相比,本文介绍的工作避免了使用脱水剂和全氟辛烷磺酸盐(PFOS)配体。文中还阐述了对操作机理的见解。
