Abstract

Phase transfer catalysis without solvent allows the selective preparation of N-allyl- and N-propargylazoles or N-(1-propenyl)- and N-(1,2-propadienyl) azoles by reaction of the parent azole with allyl or propargyl bromides. Small variations in the reaction conditions, base or temperature, afford the desired selectivity.
