2-substituted-4(3H)-quinazolinones . Iminophosphoranes also react with carbon disulfide and carbon dioxide to give the quinazolinones and respectively. Iminophosphorane , derived from 2-(o-azidophenyl)benzimidazole, reacts with isocyanates, carbon disulfide and carbon dioxide to form 6-substituted benzimidazo[1,2-c]quinazolines and respectively. In benzene at room temperature, iminophosphorane , reacts
