herein the use of glycerol as a novel solvent in the cross-coupling reaction of diaryl diselenides with vinyl bromides catalyzed by CuI. This cross-coupling reaction was performed with diaryl diselenides and (Z)- or (E)-vinyl bromides bearing electron-withdrawing and electron-donating groups, affording the corresponding vinyl selenides in good to excellent yields. The mixture glycerol/catalyst can be
我们在本文中描述了甘油在二芳基二硒化物与CuI催化的乙烯基溴的交叉偶联反应中作为新型溶剂的用途。该交叉偶联反应是用带有吸电子和给电子基团的二芳基二硒化物和(Z)-或(E)-乙烯基溴化物进行的,从而以良好或优异的产率提供了相应的乙烯基硒化物。甘油/催化剂的混合物可直接用于进一步的交叉偶联反应。
