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). The Diels- Alder reaction is one of the most important reactions in all of organic chemistry because of the applicability of it. This reaction can form

Ronak Parikh U30682934 Experiment 2: Diels-Alder Reaction: Synthesis of cis-Norbornene-5‚6-endo-dicaroboxylic anhydride Introduction: The main goal of this experiment is to perform a Diels-Alder reaction between 2‚3-dimethyl-1‚3-butadiene and maleic anhydride‚ identify the product and hydrolyze to form the dicarboxylic acid. Diels alder reactions are classified as pericyclic reaction‚ which is a reaction which involves a cyclic rearrangement of bonding electrons‚ which means

Introduction The Diels-Alder Reaction is a reaction used in organic chemistry that builds rings very efficiently (1)‚ this cycloaddition process allows for the stereoselective formation of cyclohexene rings possessing as many as four contiguous stereogenic centers (3). This reaction occurs without intermediates‚ in a single step‚ which explains the stereospecificity due to substituents not being given the chance to “switch around”. (1)These six membered rings are synthesized by reacting a dienophile

Organic Chemistry II Lab Diels Alder Reaction Purpose: In this experiment a Diels-Alder reaction was used to form the products. Cyclopentadiene and maleic anhydride were reacted together to form cis-Norbornene-5‚6-endo-dicarboxylic anhydride. 7-oxabicyclo{2.2.1}hept-5-ene-2‚3-dicarboxylic anhydride was also produced through a Diels-Alder reaction with the combination of furan and maleic anhydride.

26‚ 2015 Diels Alder Reaction Introduction: Diels Alder Reaction is the reaction of a diene with a species capable of reacting with the diene‚ the dienophile. A diene is a hydrocarbon that contains two carbon double bonds‚ while a dienophile is an electron-deficient alkene. The Diels-Alder is also called a [4+2] cycloaddition because a ring is formed by the interaction of four pi electrons of the alkene with two pi electrons of the alkene or alkyne. The product of the Diels-Alder reaction is usually

In this experiment the objective was to perform a Diels-Alder reaction using cyclopentadiene and maleic anhydride to synthesize the product‚ cis-Norbornene-5‚6-endo-dicarboxylic anhydride. The Diels-Alder reaction is one of the most important reactions in organic chemistry and was first investigated by Otto Diels and Kurt Alder in Germany. It is a [4+2] concerted cycloaddition reaction which involves a diene and a dienophile. The Diel-Alder reaction are mainly used for creating new carbon-carbon bonds
