A sequential one-pot approach to the tetrasubstituted 2H-imidazole scaffolds has been developed from disubstitutedalkynes and structurally diverse ketones. The reaction proceeds via a diketo intermediate generated from internal alkynes followed by the addition of ammonium acetate and a suitable ketone, affording a diverse range of 2H-imidazoles. Using air-moisture stable reaction conditions and inexpensive
