Micellarcatalysis offers a green alternative method for catalytic transformations by the solubilization of hydrophobic organic compounds. Biosurfactants represent a sustainable alternative to synthetic surfactants due to their biodegradability, low toxicity, and production from renewable feedstocks. In this work, we demonstrated the applicability of biosurfactant rhamnolipids in various micellar cross

biaryls in up to 92% yield. Arylhalides also undergo POPd7-catalyzed aryl-vinyl and aryl-alkyl bond formation under mild conditions. Styrenes and alkylarenes were prepared in 79-93% yield fromarylhalides and vinyl or alkylzinc reagents. The replacement of arylhalides by acyl halides provides access to ketones which were produced in up to 98% yield when POPd was used as catalyst. This approach overcomes
