Facile and efficient synthesis and herbicidal activity determination of novel 1,2,4-triazolo[4,3-a]pyridin-3(2H)-one derivatives via microwave irradiation

A novel series 1,2,4-triazolo[4,3-a]pyridin-3(2H)-one compounds were synthesized under microwave irradiation. Their structure and the herbicidal activity was determined. The compounds exhibited moderate activity. Structure-activity relationship was carried out.107
