None:
The varying stoichiometry of the lithium amide-imide ammonia decomposition catalyst under working conditions was ascertained by calculating the gas release events in the ammonia decomposition experiments. Rather than varying smoothly between amide and imide, the gas releases showed evidence of a molten state with a majority of amide stoichiometry before converting at temperatures above 460 °C to a solid with a majority of imide stoichiometry. At higher temperatures, there was indirect evidence of nitride hydride groups being formed within the catalyst structure.

Aldehydes and Ketones with Amines: Imine Formation Mechanism
Imines are formed under mildly acidic conditions. A pH of 4.5 is ideal for the reaction.
If the pH is low or the solution is too acidic, the reaction slows down in the...
Amides to Amines: LiAlH4 Reduction
Amide reduction requires two equivalents of the reducing agent, acting as a source of hydride ions. As shown in the figure, the reaction is initiated with a nucleophilic attack by the hydride ion at the carbonyl carbon to form a tetrahedral intermediate.

In the first step of the aminolysis mechanism, the amine attacks the carbonyl carbon of the acyl chloride to form a tetrahedral intermediate. In the second step, the carbonyl group is re-formed with the elimination of a chloride...
Nitriles to Amines: LiAlH4 Reduction
As shown below, the mechanism involves three steps. Firstly, the hydride ion acting as a nucleophile attacks the nitrile carbon to form an anion. In the second step, a second equivalent of the hydride ion attacks the anion to...
