| 1. | Polyphosphoric acids are used in organic synthesis for cyclizations and acylations.
|
| 2. | In the acylation reaction, AlCl 3 complexes with the product.
|
| 3. | The third reaction involved intermediate XVII undergoing acylation using acetyl chloride.
|
| 4. | For the acylation reaction a stoichiometric amount of aluminum trichloride is required.
|
| 5. | Therefore, more insulin will bind to receptors when acylation decreases, causing hypoglycemia.
|
| 6. | Acylation can be used to prevent rearrangement reactions that would normally occur in alkylation.
|
| 7. | Pseudoephedrine amides are typically prepared by acylation with an acid chloride or acid anhydride.
|
| 8. | The ratio between alkylation and acylation depends on the substrate and the reaction conditions.
|
| 9. | The compound is prepared by acylation of 2-bromopyridine via the Grignard reagent.
|
| 10. | In the Friedel Crafts acylation, acid halides act as electrophiles for electrophilic aromatic substitution.
