Diimide occurs only as an unstable intermediate in the hydrolysis of azodi-carboxylic acid, in the alkaline cleavage of benzene sulfonyl hydrazide, hydroxyl-amine-O-sulfonic acid and chloramine, in the oxidation of hydrazine, and in several other organic decomposition reactions . At room temperature it readily undergoes decomposition, disproportionation, and in the presence of symmetrical multiple bonds (like the ones in olefins) hydrogen transfer reactions ... [Pg.569]

Diimide is also formed in the thermal and base-catalyzed decomposition of benzene-, 4-methylben-zene-," 4-nitrobenzene-, and 2,4,6-triisopropylbenzene-sulfonyl hydrazide. ... [Pg.472]

A divinylbenzene-ethylene-styrene copolymer is sulfonated by 3.5-10% solutions of chlorosulfonic acid in organic solvents, e.g. chloroform or 1,2-dichloroethane at RT to yield cation-exchange resins. Porous st)rrene-divinyl-benzene-ethylvinylbenzene copolymers have also been treated with the reagent and hydrazine hydrate to form ion-exchange resins containing sulfonyl hydrazide groups. ... [Pg.250]

With 3-chloroacetanilide, the crude sulfonyl chloride could be characterized as the hydrazide, or purified by recrystallization from benzene giving 18% yield. " The 2- and 3-chloroacetanilides reacted with reagent (four to five equivalents) at 60-80 °C (4 hours) to give low yields of the sulfonyl chlorides, but chlorosulfona-... [Pg.103]
