Summary
A polymeric reagent, polystyryldiphenyl-phosphine tetrahydroborate copper, has been prepared by chemical modification of cross linked polystyrene using a fourstep reaction sequence involving a ligand exchange reaction for the binding of cuprous chloride to the phosphine resin. The reagent is very effective in the reduction of acid chlorides to aldehydes and can be regenerated easily without loss of activity.
