Abstract
Abstract CeCl 3 catalyzes the addition of Et 2 Zn to a variety of alipahtic and aromatic aldehydes and ketones in THF in the presence of TMSCl as a scavenger. Optimization of the applied solvent allowed to avoid the TMSCl mediated addition using CeCl 3·(THF) 2 or Ce (i- PrO) 3 as catalysts. This represents the first application of lanthanide compounds for the addition of Et 2 Zn to carbonyl compounds.
