Abstract
The reaction of [NPCl2](n) with substoichiometric amounts of the thiophenol
s HS-C6H4-R (R = H, Br) and Cs2CO3 in THF at room temperature, gave solutio
ns of {[NPCl2](1-x)[NP(S- C6H4-R)(2)](x)}(n) [R = H (1a), Br (1b)]. The rea
ction of the derivative with R = Br an dx = 0.3 with HO-C6H4-Br gave the ra
ndom copolymer {[NP(O-C6H4-Br)(2)](0.7) [NP(S-C6H4- Br)(2)](0.3)}(n) (2); s
imilarly, the reaction of 1 with the biphenol HO-C6H4 - C6H4 - OH gave the
random copolymers {[NP(O2C12-H-8)](0.75)[NP(S-C6H4-R)(2)](0.25)}(n) [R = H,
(3a); R = Br, (3b)] as soluble and stable white solids.
