Demethylation is the chemical process resulting in the removal of a methyl group (CH 3) from a molecule. [1] [2] A common way of demethylation is the replacement of a methyl group by a hydrogen atom, resulting in a net loss of one carbon and two hydrogen atoms. The counterpart of demethylation is methylation . ground woodpecker photos

WebE.g. The reduction of Acetic acid, methyl acetate and acetyl chloride by LiAlH 4 furnish the same ethyl alcohol. 3) The amides are reduced to amines by Lithium aluminium hydride, LiAlH 4. Especially this method is used to get secondary amines. E.g. Diethyl amine can be prepared starting from acetyl chloride as follows: WebMy guess is that it’s similar to deprotection with BBr3 if you want to look up a mechanism with that. Oxygen attacks Al, kicks off Chlorine which attacks the methyl group (SN2). Then in water, you slowly hydrate the Al to end up with Al (OH)3 and the phenol. Here’s the deprotection with BBr3:
