    18‚ 2012 Experiment 32: Identification of a Conjugated Diene from Eucalyptus oil Introduction In this experiment‚ the purpose was to prepare the Diels-Alder adduct of the unknown conjugated diene in Eucalyptus oil and determine the approximate percentage of diene in Eucalyptus oil. To discover the product of this reaction‚ isolate the adduct‚ and classify the diene from the melting point of its adduct. The unknown was one of four conjugated dienes. Maleic anhydride

    Identification of a Conjugated Diene from Eucalyptus Oil Introduction: When two carbon-carbon double bonds are positioned next to one another‚ a conjugated diene is formed. Conjugated dienes undergo a cycloaddition reaction with certain double bonds to afford cyclohexenes and related compounds. The reaction is named Diels-Alder. The Diels-Alder reaction is between 1‚3-butadiene and ethylene to produce cyclohexene + dienedienophile. The mechanism of the Diels-Alder reaction is classified as a [4+2]

    Brittany Martin 2/13/2014 Diels Alder reaction of anthracene and Maleic anhydride Reaction Scheme: Figure one shows the reaction scheme for Diels Alder reaction of anthracene and maleic anhydride Theory/Background: The Diels-Alder reaction was created in 1928 by two German chemists Otto Diels and Kurt Alder (Wade‚ Jr.‚ 2013). This reaction is best used for making six membered rings with different functional groups. The reaction is called a 4+2 cycloaddition because a ring is formed

    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

    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

    A Diels-Alder reaction was performed in this experiment. Which is a reaction that was discovered by Otto Diels and Kurt Alder. This particular type of reaction is the concerted cycloaddition among a dienophile and a diene. The Diels-Alder reaction allows for the synthesis of stereospecific rings in an efficient manner. This reaction proceed in a single step method‚ otherwise known as Nucleophilic Substitution in the second order (SN2). The Diels-Alder reaction is categorized as a pericyclic reaction
