Novel 2-aryloxy-5-(2-furfurylidene)-4H-imidazolin-4-ones 6 were synthesized by aza- Wittig reaction of vinyliminophosphorane 4 with phenyl isocyanate and subsequent condensation with various substituted phenols in the presence of catalytic amount of potassium carbonate. The products are confirmed by 1H NMR, MS, IR and elementary analysis.
