efficient method for the synthesis of 3-haloindoles has been developed. Both 3-chloro- and 3-bromoindole derivatives can be obtained in high yields by the reaction of N-electron-withdrawinggroup-substituted2-alkynylanilines with cupric halide in dimethyl sulfoxide (DMSO) within a short period of time. Investigation of the reaction mechanism reveals that two equivalents of cupric halide are necessary
