摘要

3,6-Di(pyridin-2-yl)-1,2,4,5-tetrazine(pytz)capped Pd(0) nanoparticles (TzPdNPs) as a catalyst in the Sonogashira coupling of aryl halides in aqueous medium with diminished homocoupling is reported. The methodology provides a facile route to obtain polyfunctional alkynes under ligand- and copper-free conditions. The procedure is also efficient for aryl chlorides.
