Organocerium reagents, prepared in situ by the treatment of organolithium compounds with cerium(III) iodide, exhibit characteristic reactivities toward ketones; at –65 °C, nucleophilic additions give the corresponding tertiary alcohols in excellent yields, while, at 0 °C to ca. room temperature, reductive coupling and/or reduction of the ketones prevail.
通过用碘化铈(III)处理有机锂化合物而原位制备的有机铈试剂具有对酮的特征性反应性。在-65℃下,亲核加成,得到在良好的产率相应的叔醇,同时,在0℃至约 在室温下,还原偶联和/或酮还原占主导。
