An efficient synthesis is described of the substituted azoles referred to in the title, which are precursors of an equally successful new synthetic approach to indoles, benzimidazoles and benzoxazoles. Benzazoles are synthesized almost exclusively by formation of the azole ring on to a benzene nucl
