Poly(phenylene sulfides). (Asahi Glass Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58185626 A2 29 Oct 1983 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08G075-02. APPLICATION: JP 82-67144 23 Apr 1982. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Polythiophenylenes (I, R = H, Cl, Br, I, NO2, NH2, C1-4 alkyl, C1-2 alkoxy, CN, carboxylic acid esters, dialkylamino, aldehydo, carboxy; m = 0-4) with high m.p. are prepd. in high yields from a halothiophenol (II, X = Cl, Br, I) and a hydrogen halide scavenger or from a II salt in the presence of a Ni catalyst under ordinary pressure and at a low temp. Thus, 4-bromothiophenol 21.05, tert-BuOK [865-47-4] 18.51, dibromobis(triphenylphosphine)nickel [14126-37-5] 0.41, and ethylene glycol 100 parts were mixed under N and filtered to give 10.06 parts poly(4-thiophenylene) [25212-74-2] with m.p. 25212-74-2 and 865-47-4 are just another two chemicals used in this study. 279°. .

A novel type of polycondensation of polyhalogenated organic aromatic compounds producing thermostable polyphenylene-type polymers promoted by nickel complexes

A novel type of polycondensation of polyhalogenated organic aromatic compounds producing thermostable polyphenylene-type polymers promoted by nickel complexes. Yamamoto, Takakazu; Yamamoto, Akio (Res. Lab. Resour. Util., Tokyo Inst. Technol., Tokyo, Japan). Chem. Lett., (4), 353-6 (English) 1977. CODEN: CMLTAG. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) Di- and polyhalogenated arom. compds. such as p-dichlorobenzene or 4,4'-dibromodiphenyl ether are polycondensed by dehalogenation with Mg in the presence of Ni complexes to give high yields of polyphenylenes. The Ni complexes used are (2,2'-bipyridine)nickel dichloride [22775-90-2] and bis(triphenylphosphine)nickel dibromide [14126-37-5]. The complexes catalyze the polymn. of 1,3,5-trichlorobenzene and hexabromobenzene, but also cause ring-opening polymn. of the THF solvent, forming polymers contg. arylene and polyoxytetramethylene sequences. Polymg. p-dibromobenzene in a CO atm gave a product contg. CO and p-phenylene units in a ratio of approx. 26969-37-9 and 27880-39-3 are just another two chemicals used in this study. 1:2, confirming that the polymn. proceeds on the Ni complex. .
