Cinnamic acid 1. Draw the detailed mechanism on how bromine adds to a double bond using...
Draw the mechanism of the bromination reaction between trans cinnamic acid and bromine. Be sure to include stereochemistry( wedge and dashed structures). The product obtained was the racemic mixture of (2R,3S) and (2S,3R) of 2,3-dibromo-3-phenylpropanoic acid.
Bromination of cinnamic acid. The styrene in carbon tetrachloride solution easily adds bromine at -15 ° .Why does cinnamic acid require more drastic conditions for the reaction to take place at a reasonable rate?
2. Draw the entire mechanism for the syn- addition of bromine + trans-cinnamic acid. All stereochemistry must be shown. All chirality (R, S) must be labeled for chiral centers.
3. Draw the entire mechanism for the anti- addition of bromine + trans-cinnamic acid. All stereochemistry must be shown. All chirality (R, S) must be labeled for chiral centers.
3. Draw the entire mechanism for the anti- addition of bromine + trans-cinnamic acid. All stereochemistry must be shown. All chirality (R, S) must be labeled for chiral centers. *Use backside of paper.
Why is 1,5-hexadiene added at the end of Bromine addition to trans-cinnamic acid? To neutralize any unreacted cinnamic acid molecules To make crosslinking reaction with the double bond of trans-cinnamic acid To make crosslinking reaction with unreacted bromine molecules To neutralize any unreacted bromine molecules To neutralize any molecules of HBr that might be formed as by product
Stereochemistry of bromine addition 1) To investigate the mechanism for the addition of bromine to an alkene, we will use the melting point of our brominated products. The three possible outcomes for this lab are to obtain 1)only the syn enantiomers, 2)only the anti enantiomers, or 3)a mixture of diastereomers. Match these possible outcomes to the three possible mechanisms described in the lab manual, bromonium ion, concerted Br2 activation, and carbonation 2) In this experiment we don't crystallize the final...
please provide a detailed solution. will rate asap! Match the mechanism to the alkene that is produced, trans-butene or cis-butene. Hb. D C How MC Premise Response Drag and drop to match 1 1 = A trans-butene 2 2 = B cis-butene
1) Predict the product of the reaction of 1-butene with bromine (The IUPAC name) 2) An alkyne undergoes hydrogenation to produce an alkene as follows: RC(triple bond)CR +H2 (Pd catalyst) alkene predict the product. 3) Predict the ester product of the following reaction: CH3OH + CH3CH2CH2COOH (H2SO4) PRODUCT + H20 (Express your answer using the IUPAC name) 4) Predict the carboxylic acid product of the following reaction: CH3COOCH2CH3 + H20 (H+) carbxylic acid + CH3CH2OH (Express your answer using the...
3. Draw a stepwise, detailed mechanism for the acid-catalyzed hydration reaction in question 2 above. Use curved arrows to indicate the flow of electrons. (Note: use hydronium ion, H307, in your mechanism to indicate "acidic water"). (6 pts) 4. Draw a stepwise, detailed mechanism for the reaction below. Use curved arrows to indicate the flow of electrons. (Hint: think of this reaction as a combination of addition of HX (step 1) and hydration (step 2)]. In the second step, an...
