The addition of Grignard reagents to ketones is significantly enhanced by cerium chloride with remarkable suppression of side reactions, particularly enolization. Some esters, which are prone to side reactions, also react readily with Grignard reagents in the presence of cerium chloride to give normal reaction products in reasonable to high yields.
氯化铈显着增强了格氏试剂向酮中的添加,显着抑制了副反应,尤其是烯醇化。一些易于发生副反应的酯在氯化铈存在下也很容易与格氏试剂反应,以合理到高产率得到正常反应产物。
