Controlled length polystyrene-supported PPh3 ligands are made by atom transfer radical polymerization, involving direct copolymerization of styrene and 4-diphenylphosphinostyrene (SDPP). Controlled Mn and low dispersity are obtained with low SDPP content (≤25 %). The performance of these polymeric ligands in rhodium-catalyzed hydroformylation of 1-octene is evaluated as a function of polymer length, degree of P incorporation, and P/Rh ratio.
