<p>Bicyclic dicarboxylic acids and their derivs. Title cpds. of formula (I) (where a is -O- or a divalent aliphatic hydrocarbon residue opt. interrupted by O and opt. subst. by alkyl, alkoxy, acyloxy, aryl or halogen ; A2 is vinylene opt. subst. by alkyl, alkoxy, acyloxy, aryl or halogen; R1 anr R2 are H, halogen, alkyl, alkoxyalkyl or acyloxy-alkyl; X1 and X2 are OH, halogen, alkoxy, aryloxy, -O-B-Y-, -NH-B-Y-, -N(B-Y)2 or -NZ1Z2; B is a divalent hydrocarbon residue, Y is halogen, CN, OR, SR, N(R)2, N(R)2.HCl, N(R)+3 anion, COOR, CON(R)2; R is a hydrocarbon residue or N(R)2 is a heterocyclic ring; Z1 and Z2 are H or hydrocarbyl, or Z1 is H and Z2 is acyl, OH, alkoxy, aryloxy, acyloxy, NH2 or subst. amino, or NZ1Z2 is a heterocyclic ring), which are useful as medicaments, cosmetics, pesticides, herbicides, solvent- and lubricant-additives, emulsifiers, solubilisers or adjuvants for the plastics, paper and textile industries or as intermediates therefor, are prepd. by reacting fumaric acid or a corresp. functional deriv. with a corresp. cyclic cpd. contng. 2 conjugated endocyclic double bonds (which may be used in polymeric form, monomerization taking place in the reaction mixture).</p> |
