| Abstract: | A visible light induced rapid one pot intermolecular Sonogashira coupling and 5-endo-dig cyclization in water of ortho-halophenols and terminal alkynes catalyzed by Pd] have been developed to furnish 2-aryl/alkyl benzofurans in good yields sans Ru or Ir complexes or any other additives. |
| Keywords: | Intermolecular photochemical Sonogashira coupling 5-endo-Dig cyclization Halophenols Alkynes Water |
