Abstract
A water-soluble complex Rh/PPA(Na+)/DPPEA 1 was obtained from poly(4-p entenoic acid) (PPA) and bis[2-(diphenylphosphino)ethyl]amine (DPPEA). Complex 1 is a highly active catalyst for the hydroformylation of ole fins. Some selectivity for linear aldehydes was observed in the hydrof ormylation of aliphatic olefins, while high ratios of branched aldehyd es resulted in the case of vinyl ethers. Complex 1 is also the first p olymeric water-soluble metal complex which can catalyze the conversion of vinylarenes to 2-arylpropanals in a highly chemoselective and regi oselective manner.
