N-Methyl-N-nitroso-p-styrenesulfonamide (1) was synthesized starting with sodium p- styrenesulfonate (3). Monomer 1 and sodium p-styrenesulfinate (2), also synthesized starting with 3, were polymerized and polymer of 2 was converted to corresponding free acid (9). The function of polymer of 1 as the reagent attaching the CH 2 group to the carbonyl carbon by insertion and that of polymer 9 as the catalyst for cis→ trans isomerization were ...
