Abstract

Linear phenylene-arsenical polymers built of units each of which contains one or two arsenic atoms and one or two phenylene or substituted phenylene groups, together, if desired, with an oxygen atom or an alkylene group are prepared either by (A) reacting n-butyl lithium (prepared by dissolving lithium metal in ethereal n-butyl bromide) at - 25 DEG C. with an organic dibromide to form the dilithium compound which is then reacted with a chloroarsine; or by (B) adding excess lithium to the organic dibromide in tetrahydrofuran containing some butyl bromide, removing excess lithium and converting butyl lithium into organic dilithium, and then reacting with chloroarsine. Examples describe the preparation of (I) poly - (p - phenylenephenylarsinidene [-C6H4-As(C6H5)-]n (II) Poly - (4,41 - diphenylether phenylarsinidene). (III) Poly-(m-2-methoxy-5-bromophenylene phenylaxinidene). (IV) Poly-(4,6-dimethoxy - m - phenylene phenylarsinidene). (V) Poly (9,10-anthracylene phenylarsinidene) [-C14H8-As(C6H5-]n (VI) Poly (p - phenylenearsanthrene - 5,10-diyl). (VII) Poly (p-phenylene-o-phenylene-di-arsinous acid anhydride-As, As1-diyl). <FORM:1015501/C3/1> (VIII) Poly (4,41 - diphenylene phenylarsinidene). (IX) Poly (p-phenylene-hydroxyarsinylidene) <FORM:1015501/C3/2> (X) Poly (p-phenylene - hydroxyarsinylidene-p-xylylenehydroxyarsinylidene). <FORM:1015501/C3/3> (XI) Poly (p - phenylene - hydroxyarsinylidene -ethylenehydroxyarsinylidene). <FORM:1015501/C3/4> Polyorganoarsinic acids may be useful as ion -exchange resins, or the arsenic acid groups may be reduced, e.g. with SO2 and HCl to give polychloroarsines which, reacted with a Grignard reagent or with an organic lithium compound, give organo-substituted polyarsines.
