Procedure

Anhydrous nickel(II) chloride (60 mg, 0.46 mmole), triphenylphosphine (800 mg, 3.05 mmole), sodium iodide (180 mg, 1.2 mmole), and activated zinc powder (1.2 g, 18 mmole) are placed into a 25 ml flask under an inert atmosphere along with 7 ml of anhydrous N-methylpyrrolidinone (NMP). This mixture is stirred at 50° C. for about 10 minutes, leading to a deep-red coloration. A solution of 3.4 g (11.5 mole) of 2,5-dichlorobenzenesulfonylmorpholine, which is prepared by the reaction of 2,5-dichlorobenzenesulfonyl chloride with morpholine, in 8 ml of anhydrous. NMP is then added by syringe. After stirring for 60 hours, the resulting highly viscous solution is poured into 100 ml of 1 molar hydrochloric acid in ethanol to dissolve the excess zinc metal and to precipitate the polymer. This suspension is filtered and triturated with acetone to afford, after isolation and drying, solid polyparabenzenesulfonylmorpholine.
