Abstract:
A simple and regioselective cross-coupling of styrene oxides with arylboronic acids in the presence of Rh(PPh3)3Cl in biomass-derived γ-valerolactone has been developed. The reactions proceeded smoothly to give 1,2-diaryl ethanols as the predominant products in moderate to good yields.
Keywords:styrene oxides, arylboronic acids, rhodium catalysis, regioselectivity, γ-valerolactone, green solvent.
