文摘

Gallic acid derived in situ PdNPs is developed as reusable catalyst for Sonogashira reactions. Natural feedstock is used as additive. The catalyst is easily accessible, mild and avoids use of unfavorable ligands and toxic solvent. The new catalyst is effective for diverse range aryl halides and terminal acetylenes.
