在催化量的[ReBr（CO）（3）（THF）]（2）存在下，杂芳族化合物借助于导向基团亚胺部分与乙炔在导向基团的相邻位置上区域选择性地加成，以良好至优异的产率进行乙炔的氢化芳基化。类似地，杂芳族化合物与丙烯酸酯和异氰酸酯反应，得到相应的氢芳基化产物。(C)2008爱思唯尔有限公司版权所有。
With the aid of a directing group, an imine moiety, heteroaromatic compounds add to acetylenes in the presence of a catalytic amount of [ReBr(CO)(3)(THF)](2) at the adjacent position of the directing group regioselectively to give hydroarylation of the acetylenes in good to excellent yields. Similarly, heteroaromatic compounds react with acrylates and isocyanates to give the corresponding hydroarylation products under rhenium catalysis. (C) 2008 Elsevier Ltd. All rights reserved.
