Which will give better neuclophilic addition reaction?

Click For Summary
SUMMARY

The discussion centers on the nucleophilic addition reactions of two specific compounds: Ph---CO---O----CO----CH3 and Ph---CO---O----CO----CH2-----CH3, both involving phenyl groups and carbonyl functionalities. The initial hypothesis suggests that the carbonyl carbon adjacent to the methyl group will be the primary site of attack due to electron donation from the phenyl ring, making it less attractive to hydroxide ions. The second compound, modified with a methyl group at the meta position, is also predicted to undergo a similar reaction, with the non-phenyl carbonyl group being attacked. The discussion highlights the importance of understanding the influence of substituents on nucleophilic attack in anhydrides.

PREREQUISITES
  • Understanding of nucleophilic addition reactions

NEXT STEPS
  • Study the mechanism of nucleophilic addition to anhydrides
  • Learn about the effects of substituents on nucleophilic attack in aromatic compounds
  • Explore the reactivity of different carbonyl compounds in nucleophilic reactions
  • Investigate the role of resonance in stabilizing reaction intermediates
USEFUL FOR

Chemistry students, organic chemists, and researchers focusing on reaction mechanisms and the reactivity of carbonyl compounds.

Initial Compound is like this
Ph---CO---O----CO----CH3.(Ph means phenyl)
It is reacted with H3O+. What will be product? I think first attack will be at carbonyl carbon near methyl. Because phenyl ring will donate electrons to carbonyl group near it and make it less attractive towards hydroxide.
Now change the compound.
Ph---CO---O----CO----CH2-----CH3.(Ph means phenyl)
add methyl at meta position in phenyl (with respect to carbonyl group attached to benzene ring).
What will happen when this will reacted with water. I think same kind of thing as it happen in last case. Non phenyl carbonyl group will be attacked.

Am i correct in both cases??
if not then please point out the mistake.
thanks!
