(to the tune of America the Beautiful)
The carbon end is plus.
A nucleophile will thus attack
The carbon nucleus.
A Grignard yields an alcohol
Of types there are but three.
It forms a bond to correspond
From C to shining C.
Requires an aldehyde.
For tertiary, a carbanion
And ketone may collide.
And Grignards add formaldehyde,
The product's primary.
They stick like glue to CO2
Join C to lonely C.
(to the tune of "The Battle Hymn of the Republic")
It forms a hydrazone, of course, and water leaves the scene.
An NH from the NH2, hydroxide will attack.
Resonance occurs and then the carbon grabs H back.
Glory, Glory, It's Wolff-Kischner!
Glory, Glory, It's Wolff-Kischner!
Reduce the carbonyl and then the side-chain now is plain.
Now add a little heat, the N2 leaves without a fuss.
The carbon gets a hydrogen producing an alkane.
Now the carbon chain is plain.
Glory, Glory, It's Wolff-Kischner!
Glory, Glory, It's Wolff-Kischner!
Reduce the carbonyl and then the side-chain now is plain.
Oh, My Ketone!
(to the tune of "Oh, My Darling Clementine")
Oh, my ketone! Oh, my ketone!
And my primary amine.
You reacted, lost some water and
You formed a new imine.
Now the lone pair on the N then
Bonds with carbonyl C.
Pi electrons go to O, a
Proton shifts fast as can be.
Now the O is feeling greedy
Grabs an H from OH3.
Free electrons from the N then
Form a pi bond, water leaves.
Now the N is protonated
And a plus charge can be seen.
So the water yanks the H off
And we've formed a new imine.
Oh, my ketone! Oh, my ketone!
And my primary amine.
You reacted, lost some water and
You formed a new imine.
The Aldol Reaction
(to the tune of the Hokey-Pokey)
You put a strong base in,
It takes the alpha-H out:
This forms an enolate.
That's what this carbonyl's about.
The enolate will resonate,
The charge is shared by O.
That's what aldol's about.
The enolate attacks
Another carbonyl about.
A new bonds forms;
It's really neat without a doubt.
A beta-hydroxycarbonyl is the result.
That's what aldol's about.
