Abstract
The activity and efficiency of anhydrous CeCl3 depend strongly on the drying procedure. Deactivation of CeCl3 occurs during the drying proce ss as a result of hydrolysis by the hydrate water, when heating above 90 degrees C. The highly active CeCl3, prepared by an improved drying procedure, is demonstrated to activate rapidly (in catalytic and stoic hiometric amounts) ketones at room temperature, providing excellent ad dition of organometallic reagents.
