IR mssm cm The Diels-Alder reaction is categorized as a pericyclic reaction, which involves the overlap of spatial orbitals as well as the hybridization and delocalization of the molecules.
Diels-Alder Synthesis, A peak at cm-1 accounted for the carbonyl functional group, while a peak at cm-1 accounted for the alkene bond. Finally, peaks at Based on the interaction between a conjugated diene and a dienophile, different stereoisomeric compounds are formed. In a 25 mL Erlenmeyer flask, maleic anhydride 1.
The distinction of the presence of the endo isomer was proven by analyzing physical properties of both possible isomers. Interesting products of the Diels-Alder reaction are cyclic compounds with chlorine-containing substituents that act as powerful insecticides.
Due to the interaction and arrangement of a cyclic diene and a dienophile, an endo and exo product can be formed characterizing the reaction as stereo- and regioselective. Regarding the 13C NMR, a peak appeared at After heating for about 10 minutes and magnetically stirring, tiny solids still remained.
Insecticides have been commonly used to treat pests in various types of fruits, vegetables, and crops. In addition, it exhibited two peaks at 3.
In addition, this reaction synthesizes compounds that are otherwise difficult to obtain, such as bridged bicyclic compounds. 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. Finally, two peaks at 1. A key characteristic of these reactions is their stereospecificity.
The exo isomer is the thermodynamic product because it is more stable.
