Poly- sulfonyl

A polymer with a sulfone group on every other unit of the chain was obtained by the oxidation of 214 with H202 [Eq. (32)]. Thus, poly(sulfonyl-l,4-phenylenethio-l,4-phenylene) (PSPT) was synthesized in the presence of H202 and CF3C02H in CHC13 via a poly(sulfonium cation) [121]. [Pg.601]

The following products are usually contained in the reaction mixture produced by sulfochlorination 1980 mono-, di-, and poly-sulfonyl chlorides chloro-mono-, -di-, and -poly-sulfonyl chlorides alkyl chloride and unchanged starting material of which the last two are unhydrolysable neutral oils. The individual products obtained on sulfochlorination of aliphatic hydrocarbons of low molecular weight can be separated by distillation, but it has also been found that the mono- can be separated from the poly-sulfonyl portions by treating the mixture with at least a five-fold amount of pentane and cooling to — 30°.206... [Pg.627]

Shai and Patchornik showed that poly(sulfonyl chloride) (prepared by chlorosulfonation of a macroporous resin) is an excellent reagent for the formation of 1-hydroxybenzotriazole (HOBt) esters of N-blocked amino acids, as in Scheme 41. [Pg.813]
