| Abstract: | Under the microwave irradiation, the 1,4 bis(2 benzimidazolyl)benzene and 1,3 bis(2 benzimidazolyl)benzene were synthesized respectively by condensation of o phenylenediamine and p phthalic acid or m phthalic acid in polyphosphoric acid.The reaction time was 12 min,the yield was 77% and 84% respectively.Compared with the conventional synthesis,the rate of reaction was up to 50 and 20 times faster respectively under microwave irradiation than by conventional method,and the yield was comparable. |
