A novel green protocol for ligand free Suzuki–Miyaura cross-coupling reactions in WEB at room temperature

A highly efficient green protocol for palladium acetate-catalysed ligand-free Suzuki–Miyaura cross-coupling reactions in neat ‘water extract of banana (WEB)’ was developed. This method offers a mild, efficient and highly economical alternative to the existing protocols since the reaction proceeds in WEB at room temperature in air at very short reaction times (5–90 min) under ‘ligand/external base/external promoter/organic medium’ free conditions.
