pedot nanofiber/pd(0) composite-mediated aqueous mizoroki–heck reactions under ultrasonic irradiation: an efficient and green method for the c–c cross-coupling reactions

An environmentally benign and highly efficient procedure for the c–c cross-coupling reactions of aryl halides with olefinic compounds has been developed under ultrasonic irradiation in water in the presence of pedot nanofibers/pd(0) composites (pedot-nfs@pd) as a new recyclable catalyst. pedot-nfs@pd catalyzed the reaction efficiently without using any other harmful organic ligands. cleaner reaction profile, easy workup procedure, high yields and short reaction time duration are some remarkable features of this method. the utilization of ultrasound irradiation offers a fast, clean and versatile synthetic tool that is often unavailable by conventional methods. moreover, the catalyst can be recovered by simple filtration and reused several times without significant loss of activity.
