Using the cyclopentadiene and a forward diels-alder reaction cisnorbornene -5,6-endo-dicarboxylic anhydride will be synthesised a hydrolysis reaction on the anhydride will be performed to yield cis-norbornene -5,6-endo-dicarboxylic acid h2so4 will then be used to dehydrate the dicarboxylic a cid to give an unknown compound (compound x. View lab report - diels-alder reaction synthesis of cis-norbornenr-5,6-endo-dicarboxylic anhydride from chm 2211l at university of south florida i introduction diels alder reactions are known as.
Introduction diels-alder reactions are a very important method of forming 6 membered rings in a single step in this experiment maleic anhydride is reacting with 1,3- cyclopentadiene to form cis-norbornene 5,6-endo dicarboxylic acid anhydride the product will be isolated by vacuum filtration and weighed the purity of the product will be determined using melting point.

Mechan cyclopentadiene maleic anhydride cis-norbornene-5,6-endo-dicaroboxylic anhydride diene dienophilediels-alder product side reaction the side reaction which occurs during the production of cis-norbornene-5,6-endo-dicaroboxylic anhydride is the dimerization of the diene. Diels-alder reaction: synthesis of cis-norbornene-5, 6-endo-dicarboxylic anhydride introduction: the diels-alder reaction is a [4+2] cycloaddition of a conjugated diene and a dienophile.
Diels-alder reaction: synthesis of cis-norbornene-5, 6-endo-dicarboxylic anhydride introduction: the diels-alder reaction is a [4+2] cycloaddition of a conjugated diene and a dienophile this type of reaction was named for otto diels and kurt alder who were the first to investigate this reaction (weldegirma, 2012.
Reaction mechanism the scheme below depicts the concerted mechanism of the diels-alder reaction of cyclopentadiene and maleic anhydride to form cis-norbornene-5,6-endo-dicarboxylic anhydride results and discussion when combining the reagents, a cloudy mixture was produced and problems arose in the attempt to completely dissolve the mixture. Cis-norbornene-5,6-endo-dicarboxylic anhydride in this laboratory exercise we will synthesize the compound cis-norbornene-5,6-endo-dicarboxylic anhydride a compound which, in and of itself, is of relatively little importance however, the synthetic method used to generate this compound, the diels-alder reaction, is extremely important.
Chem 322: diels-alder reaction: preparation of cis-norbornene-2,3-endo-dicarboxylic anhydride introduction: in 1921, otto diels and kurt alder discovered that certain alkenes and alkynes can undergo a 1,4.
Synthesis of cis-norbornene-5,6,-endo-dicarboxylic anhydride o o o + o o o before lab: read about diels alder reactions and recrystallization materials: dicyclopentadiene, 30 ml (mw 132) maleic anhydride, 6 g (mw 98, mp 52 to 54 °c) toluene, 30 ml methylene chloride and pet ether precautions: keep all glassware and solvents dry avoid contact with maleic anhydride dust.
