These ligands were incorporated into water-soluble rhodium-PNP complex catalysts that were used to regioselective hydroformylation of a series of terminal arylalkenes,providing efficient access to rac-α-aryl propionaldehydes in good to excellent yield(up to 97%) and branched-regioselectivity(up to 40:1 b/l ratio). Furthermore, gram-scale and diverse synthetic transformation demonstrated synthetic application of this methodology for non-steroidal antiinflammatory drugs.展开更多
