Abstract We report on a one-pot, multistep process in which styrene derivatives are selectively hydroformylated to give branched aldehydes, which in turn, are condensed with reactive methylene compounds (malononitrile, ethyl cyanoacetate), and then hydrogenated. The process takes place at 80 C under 20.7 bar H 2 and 20.7 bar CO in the presence of [Rh (cod) Cl] 2 and Na [Ph 2 P-3-(C 6 H 4 SO 3)], which have been co-entrapped within ionic ...
