Small Mechanism Pointers Flashcards
Synthesis of tertiary alcohols
Unable to stop ketone intermediate as once the ketone is formed, ketones are more reactive than esters therefore ketone will not stop reacting continuously.
Protonation with gringard reagents
Protonation step destroys a Grignard reagent so once something is protonated it usually means the number of alkyl groups have been added that are needed and no more Gringnard is needed.
Nucleophilic addition of a/B-unsaturated carbonyls
Reaction is also named: Micheal Reaction, Conjugate addition, 1,4-addition.
If secondary alkyl halide, what determines if it goes via SN1 or SN2
You have to look at solvent type!
If solvent contains (-OH) inc WATER then = SN1
If solvent contains (C=O) then = SN2
