| 1. | Ammonolysis of phthalonitrile gives to diiminoisoindoline.
|
| 2. | Alternatively acetamide can be obtained in excellent yield via ammonolysis of acetylacetone under conditions commonly used in reductive amination.
|
| 3. | Via the intermediacy of biguanidine, this ammonolysis step affords salts of the guanidinium cation ( see below ).
|
| 4. | The R 3 Si NH 2 groups resulting from the ammonolysis reaction form silazane units by splitting off ammonia.
|
| 5. | For the industrial manufacture of perhydropolysilazane [ H 2 Si NH ] n, ammonolysis in a solvent is the standard process.
