This may be theoretical and unknown but I am wondering how LiAlH4 exactly reacts with an amide.
My book refers it as a hydrid ion makes an nucleophilic attack on the alpha-carbon, forcing the pi-bound of Oxygen to go up to itself and makes an negative charge and then Al is steps in and bind oxygen, making it a good leaving group, so that nitrogen can make a pi-bound to the alpha-carbon and become a cation. (Iminium Ion).
A new nucleophilic attack by a hydrid ion from a new LiAlH4 removes the pi bound between N and C and neutralize the molecule into an amine.
My question is here, what is the positively charged lithium's role? I would I be wrong to assume it destabilize the oxygen's pi-bound (due to it negative polarity) to the alpha carbon at first, so a nucleophilic attack can occur?
