Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.H2SO4 protonates carbonyl oxygen which eventually increases electrophilicity in carbonyl c Uske bad Acetone is tautomerised to become enol then do nucleophile electrophile wala reaction sir also you know that H2SO4 heating in the thing remove water and give unsaturated ketone aise hi baki wale too go under same process iske bad yk dehydration and decarbonyl and fir system tumhara usi ans me ayega benzene with 3 methyl
@Prachi hey
Iske baad kya karna hai ???
Is it fine I write here or pen paper
If you are okay, then pen paper...
Ok lemme see whatever I said is right yaa galat bhi hogaya
My discord is abit lagging I'll send you by tomorrow morning
Sorry
Thank you sir 🙏
But, sir, how do we convert this into one another and, also in the third structure how did the ketone come in
haha @Enamine bhai?
koi vishesh tippani?
enol of acetone attacks protonated acetone heat se water will go from tertiary carbinol centre e1 jaise
acetone enol adds to mesityl oxide at the beta c
dehydration furnishes the trimeric dieneone
the dieneone is protonated at one alkene to give a tertiary allylic carbo cation
then a intramolecular attack by other double bond closes ring
ring banegi
h2so4 converts the cyclohexenone into a tritertiary carbinol through reversible enolization
fir wo apni position pakad lete h
@Prachi ji
Oh, thanks
Idea to lag gaya kaise karna hai
Kal RT hai to test dene ke baad ek baar firse try karke bataungi ki hua ki nahi...
np prachi ji
Idk why but I've always felt like this reaction is a far stretch steric hindrance ki vajah se you'll get ton of mixed products
But yeah I can think of drawing a mech anyways
Kinda late I know but here you go
I’ve kinda skipped some parts so please fill in where you think I’ve not explicitly mentioned something
If not, then ask
This is how you'll approach this
Enol form banake aldol karvao
Acid is there only to protonate
2 times self aldol then 1 time intramolecular aldol
