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 by four pi electrons in the diene interacting with two pi electrons of the alkene or alkyne (Wade‚ Jr.‚ 2013). In this experiment anthracene was used as the diene and considered to be electron rich in the reaction. Maleic anhydride was the electron poor dienophile used in the reaction. The reaction converted two pi bonds into two

Substrates with A [pic]B usually add to the metal with retention of an A[pic]B single bond. For example‚ aldehydes‚ ketones‚ alkenes and alkynes‚ particularay with electron withdrawing substituents‚ can undergo reactions which amount to an oxidative addition to the metal: [pic] Of course the readiness of the metal center to react with potentially oxidative substrates

Comparing alkanes and alkenes Aim: Is cyclohexane more or less reactive than cyclohexene in the presence or absence of light Hypothesis The cyclohexene will reactive the fastest because being an "ene" it has a electron rich area making it more reactive than cyclohexane but neither one of the will react without light Materials * 4x 250ml conical flasks * 2 rubber stoppers * Aluminium foil * Cyclohexane * Cyclohexene * Bromide water * Measuring cylinder

Wittig Reaction and Photoisomerization Abstract: For this laboratory experiment stilbene was produced through a Wittig reaction with benzyltriphenyl phosphonium and benzaldehyde producing a form of stilbene (Figure 1). This reaction favored a crude Z-Stilbene crystal product over its E counterpart. When Z-Stilbene underwent photoisomerization with iodine for 1 hour it reconfigured almost exclusively into its more stable counterpart E-Stilbene. The reaction produced very low yield of 6.3% due

Notes Aldehydes and Ketones The major similarity between an aldehyde and a ketone is the carbonyl group. A carbonyl group is a carbon atom doubly bonded to an oxygen atom. [pic] Both molecules have a carbonyl group‚ the difference the number of carbons bonded to the carbonyl carbon. An aldehyde will have none or one and a ketone will have two carbons. All aldehydes‚ except formaldehyde‚ will have a hydrogen atom on one side of the carbonyl carbon and at least on carbon on the other side

Old Dominion University ORGANIC 214 Alkene Addition Submitted by: Alkene addition: Bromination of (E) Stilbene Introduction: In this lab we used the greener approach‚ which involves the addition of bromine across a double bond. When bromine reacts with E-stilbene (trans-1‚2-diphenylethene)‚ two new chiral carbons are created from the sp2 carbons‚ therefore 3 different dibrominated stereoisomers are possible: meso-(1R‚2S)‚ or the raceminc mixture-(1R‚2R) or (1S‚2S)-dibromo-1‚2-diphenylethane
