Mg-promoted reduction of benzophenones in the presence of ethyl trifluoroacetate and trimethylchlorosilane in N-methyl-2-pyrrolidinone afforded the corresponding cross-coupling products, which were easily transformed into C-trifluoroacetylated compounds of benzophenones through desilylation by tetrabutylammonium fluoride.
在三氟乙酸乙酯和三甲基氯硅烷中,在N-甲基-2-吡咯烷酮中,Mg促进的二苯甲酮还原反应提供了相应的交叉偶联产物,这些产物很容易通过四丁基氟化铵的去甲硅烷基化反应转化为C-三氟乙酰化的二苯甲酮化合物。
