When an aryl iodide bearing an electron-withdrawing group at the ortho position was milled together with bismuth shots and calcite grains in the presence of Cu powder and CuI using a laboratory ball mill, the corresponding ortho-functionalized triarylbismuthane was obtained in moderate to good yield.
当使用实验室球磨机在铜粉和 CuI 存在下将邻位带有吸电子基团的芳基碘化物与铋丸和方解石颗粒一起研磨时,以中等至良好的收率获得了相应的邻位官能化三芳基铋烷。
