Maleic Anhydride Derivatives

3-[(2,4,6-Trichloroanilino)carbonyl]prop-2-enoic acid

“…It is an important raw material used in the manufacture of unsaturated polyester resins, surface coatings, lubricant additives and agricultural chemicals (Budavari, 1989). Extensive descriptions of the chemistry of maleic anhydride and its derivatives have been published (Luskin, 1974;Flett & Gardver, 1952). The high reactivity of maleic anhydride is due to the presence of a double bond in conjugation with two carbonyl O atoms.…”

The Tetrahydrophphalic Acids

“…The Diels-Alder reaction itself has been amply covered by reviews (76,102). The specific application of the method to the synthesis of the cfs-4 anhydride has also been thoroughly covered and compilations of references are available (43, 55). A method of analysis for 4-vinylcyclohexene as a contaminant in the anhydride preparation has been developed (123).…”

“…No other review has dealt specifically with the isomeric tetrahydrophthalic acids. Some of the synthetic methods have been covered in reviews of the Diels-Alder reaction (55,76,102), and some of the useful applications of derivatives of the 4 acid have been included in practical reviews on maleic anhydride adducts (56,57). For this review the literature has been covered through 1954.…”

New Organic Compounds for Insect Repellent Research.

“…The appropriate aldehyde was then condensed (1) with the N-amino-oxabicyclo compound to give the desired substituted SchifFs base. N-anilino-7-oxabicyclo[2.2.l]hept-5-ene-2,3-dicarboximide was prepared in good yield by allowing the afore-mentioned anhydride to react with phenylhydrazine (3).…”
