We report a general protocol for the direct C-H etherification of N -heteroarenes. Potassium tert -butoxide catalyzes halogen transfer from 2-halothiophenes to N -heteroarenes to form N -heteroaryl halide intermediates that undergo tandem base-promoted alcohol substitution. Thus, the simple inclusion of inexpensive 2-halothiophenes enables regioselective oxidative coupling of alcohols with 1,3-azoles, pyridines, diazines, and polyazines under basic reaction conditions. |
