Grignard addition to a ketone template
Free template. Download it, or open it in MolDraw to change it first.
MeMgBr adds to acetone; aqueous acid work-up gives tert-butanol. New C–C bond marked.
Mechanism step by step
An organomagnesium reagent adds to C=O; acid work-up gives the alcohol
- Nucleophilic addition – The C–Mg bond attacks the C=O carbon
- Acid work-up – The alkoxide is protonated
Key points
- Dry ether or THF: water destroys R–MgBr (it is a strong base).
- Aldehydes give 2° alcohols, ketones 3°, formaldehyde 1°.
- Esters add two equivalents to give 3° alcohols; CO₂ gives carboxylic acids.
- Add the work-up acid only after the addition is complete.
Drawn with 39 atoms, 7 arrows, 8 shapes – every one editable in MolDraw.
