atmospheric pressure and −78°C, affords diarylalkylcarbinols in good yields. Alkyl chlorides do not react under similar experimental conditions. This feature makes the reaction particularly useful for the synthesis of alcohols functionalized in the alkyl chain through subsequent reactions of the diaryl(chloro)alkylcarbinols. The procedure can also be adapted to afford substituted cyclic ethers. If the reaction
在烷基溴化物RBr存在下,芳基锂的THF溶液(芳基= Ph,邻茴香基)的羰基化反应;在大气压和-78℃下,以良好的收率得到二芳基烷基甲醇。烷基氯在相似的实验条件下不会发生反应。该特征使得该反应对于通过二芳基(氯)烷基羰基醇的后续反应来合成在烷基链上官能化的醇特别有用。该方法也可以适用于提供取代的环醚。如果该反应在二溴代烷烃的存在下进行,则只有一个溴原子反应,得到有用的合成中间体二芳基(溴代)烷基甲醇。用仲和叔烷基溴化物以可变的产率得到二芳基烷基醚。
