A microwave-assisted general method for the synthesis of 2-aminovinyl benzimidazoles has been developed. Treatment of the 1,2-phenylenediamines and N-arylated/N,N-dialkylated 3-aminoacroleins with bis(cyclopentadienyl)zirconium(IV) dichloride (Cp₂ZrCl₂) as the catalyst under microwave irradiation for 3-5 min followed by in situ MnO₂ oxidation afforded thirteen 2-aminovinyl benzimidazoles in good yields.
