Abstract
|
<B>Summary:</B> A first route to the isomerisation of <I>erythro</I>- and <I>threo</I>-2,3-disubstituted succinyl units in alternating alkene-maleic acid copolymers is presented. The isomerisation reactions of the disodium salt of ethene-maleic acid copolymer were carried out in aqueous solution at 180-240 °C in an autoclave. It is demonstrated that the <I>erythro</I>-content can be changed from 17% up to 67%. The dissociation of methine C<IMGSRC="/giflibrary/12/bond.gif"BORDER="0">H bonds with the intermediate formation of a sp<SUP>2</SUP> hybridised carbon is proposed as the mechanism.
