Abstract

Nucleophilic substitution reactions of N -heterocycles such as imidazole, benzimidazole, indole and pyrazole as well as NH2 or OH containing heterocycles, with electron-deficient aryl halides in the presence of t-BuOK or K2CO3 as base and DMSO as solvent are reported. A series of N -aryl azoles, unsymmetric diaryl ethers and diaryl amines were obtained in good yields.
