α-Ketoacids can be easily synthesized with satisfactory yields and selectivities by carbonylation of aryl halides and secondary benzyl halides under very mild conditions. The reactions are catalyzed by Co2(CO)8 in alcoholic solvents; the presence of a methyl source (dimethyl sulfate or methyl iodide) is necessary for the carbonylation of the aryl halides. Base, temperature and solvent have large effects on the
通过在非常温和的条件下对芳基卤化物和仲苄基卤化物进行羰基化,可以轻松地以令人满意的产率和选择性合成α-
酮酸。该反应在
乙醇溶剂中由Co 2(CO)8催化。对于芳基卤化物的羰基化,必须存在甲基源(
硫酸二甲酯或甲基
碘)。碱,温度和溶剂对反应过程有很大影响。
