5. a) Draw the major 1,2-addition product and the major 1,4-addition product of each of the following reactions. Label each product as either the 1,2-addition product or 1,4-addition product and as either the thermodynamic or kinetic product. (12 pts) H" catalyst H catalyst b) Consider the reaction of a nucleophile with conjugated carbonyl. Provide an example of a nucleophile that would favor the 1,2-addition product and explain why. Provide an example of a nucleophile that would favor the 1,4-addition product...
4. Write the 1,2 and 1,4 products of addition of HBr to 1,3-hexadiene. Write the complete stepwise mechanism. Which product is the major if the reaction is taking place at 40°C? (4 points)
what would be the major products of this HBr addition to an
alkene?
What would be the major product(s) of this HBr addition to an alkene? HBT Br Br. Br x Br Br Br + enantiomer + enantiomer 11 IV III IV
Is this correct?
16) Provide the structure of the major product which results from 1,4-addition of HBr to the diene shown below. (3 pts)
Please explain why this is a 1,4 addition reaction and what the
1,2 addition reaction would look like:
Nu nN: +
When 1,4-dimethylcyclohepta-1,3-diene is treated with HBr at an elevated temperature, the 1,2 product predominates rather than the 1,4 adduct. Explain and draw the 1,2 and 1,4 products.
