摘要：

A variety of bis(oxazoline)palladium(II) complexes were prepared and tested in the cyclopropanation of ethyl (E)-cinnamate with diazomethane. Although an enantioselective process was never realized, effects of substitution on the ligand, catalyst loading studies, and other investigations led to a mechanistic proposal wherein partial or complete ligand dissociation occurs (depending on the ligand structure) during the course of the cyclopropanation event.
