This paper describes a facile, efficient, and clean synthesis of various pyrazolones by employing T3P as a catalyst and performing the reaction under microwave irradiation. This two-step, one-pot reaction proceeded readily and tolerated a variety of functional groups. A wide range of pyrazolone derivatives were obtained in good to excellent yields. A one-pot, two-step procedure for the synthesis of pyrazolones is presented. This method, which uses T3P and microwave irradiation, is particularly easy to carry out and offers a notable alternative to the strongly acidic conditions that are generally employed with other synthetic approaches.
