acetic anhydride pyridine acetylation
THE ACTION OF ACETIC ANHYDRIDE AND PYRIDINE ON AMINO
A control experiment was per- formed in which phenylaminoacetic acid was heated with acetic anhydride in absence of pyridine No loss of carbon dioxide occurred |
Acetic Anhydride
Acetic anhydride can be used with a basic catalyst such as pyridine This combination promotes smooth reactions and has great solvent power Pyridine acts as |
Facile and Efficient Acetylation of Primary Alcohols and Phenols with
3 déc. 2013 Pyridine is a popular catalyst for the acetylation of alcohols using acetic anhydride but is toxic |
Acetylpyridinium ion intermediate in pyridine-catalyzed hydrolysis
and for the pyridine-catalyzed acetylation of 10-3 M toluidine and anisidine by acetic anhydride establish that these transacylation reactions proceed |
SUPELCO
Pyridine may also react with acetic anhydride however |
Synthesis of (±)-Hydroxytremetone
acetic anhydride in pyridine gives 2-(a-hy- droxyisopropyl) - 5 - acetyl - 6 - acetoxycoumaran. (VIII b) m. p. 155°G |
THE VOLUMETRIC ESTIMATION OF HYDROXYL GROUPS IN
and inconvenient to execute. Acetylation of hydroxy organic compounds with an excess of acetic anhydride in pyridine generally proceeds smoothly and to. |
Quantitative Acetylation of Amines by Means of Acetyl Chloride and
tially in modifying theusual acetic anhydride- pyridine acetylation mixture by the substitution of acetyl chloride for the anhydride the acetyl. |
Acetylation of III with acetic anhydride and pyridine gave diacetyl
Acetylation of III with acetic anhydride and pyridine gave diacetyl leuconolide-A3 5 18- hemiacetal (IV) |
Analysis of the factors influencing the acetylation rate of wood
vation energy of acetylation was also estimated. In a swell- ing test it was found that wood swells thoroughly in acetic anhydride even without pyridine |
