The synthesis of unsymmetrically substituted biaryls via palladiumcatalysed coupling of aryl halides with arylboronicacids was found to produce biaryl by-products where one aryl was derived from the triphenylphosphine ligand. The use of substituted triphenylphosphine ligands to minimise this side reaction was investigated.

Unsymmetrical biaryls are obtained in high yields from cross coupling of arylboronic acids with haloarenes in the presence of a base using palladium acetate as a catalyst for reactions in aqueous ethanol at ambient temperature in the absence of oxygen.
