The reaction of [NPCl 2 ] n with substoichiometric amounts of the thiophenols HS—C 6 H 4 —R (R = H, Br) and Cs 2 CO 3 in THF at room temperature, gave solutions of {[NPCl 2 ] 1‐ x [NP(S—C 6 H 4 —R) 2 ] x } n [R = H ( 1a ), Br ( 1b )]. The reaction of the derivative with R = Br and x = 0.3 with HO—C 6 H 4 —Br gave the random copolymer {[NP(O—C 6 H 4 —Br) 2 ] 0.7 [NP(S—C 6 H 4 —Br) 2 ] 0.3 } n ( 2 ); similarly, the reaction of 1 with the biphenol HO—C 6 H 4 —C 6 H 4 —OH gave the random copolymers {[NP(O 2 C 12 ‐H 8 )] 0.75 [NP(S—C 6 H 4 —R) 2 ] 0.25 } n [R = H, ( 3a ); R = Br, ( 3b )] as soluble and stable white solids.
