We used 1.05g of p-aminophenol, 1ml of acetic anhydride, and I got 44.37g of product. Am I doing something incorrectly or is 3020% really the percent yield? Thanks. The total mass of products won't exceed the total mass of the reactants Logged "Say you're in a [chemical] plan...
This chapter discusses the synthesis of O-Acetylhomoserine. Homoserine is acetylated with acetic anhydride in a strongly acidic medium that prevents N-acetylation. Homoserine lactone is formed as a side product, which is readily separated. The general method was described some years ago and applied ...

Deoxynucleosides, dNMPs, dNTPs, AMP, ADP and ATP were all of >99% purity. Acetic anhydride and H3PO4 (85%) used for the synthesis of acetyl phosphate were ACS grade. Taq DNA polymerase and broad range (10–200 kDa) molecular weight markers were from New England Biolabs (MA, USA)...
Ten novel anthranilic diamides compounds containing fluorine and benzothiazole compounds were sythesized after benzoic acid containing fluorine unite chloridized by thionyl then coupled with 2-aminobenzoic acid,and cyclized in the existence of acetic anhydride,then coupled with substituted benzo[d]thiazol-...
Heating the title compounds 1 at reflux in acetic anhydride yields quinoxalines 3 and 4 via a presumed aryliminoiminyl radical 5, resulting from homolytic cleavage of the N O bond in the intermediate ester 2. The observed regioselectivity of the reaction is also rationalized by implicating such ...
and found that the coupling of the aldehyde-terminated D unit and the A-end groups could be quantitatively finished in the presence of acetic anhydride within 15 minutes at room temperature. Compared with the conventional method, the high reaction efficiency of our method is related to the ger...
The DA reaction was carried out in tetrahydrofuran as a solvent, as well as in bulk, followed by aromatization of sodium acetate intermediates in the presence of acetic anhydride. All the polymers were characterized by elemental analysis, IR spectral studies and thermogravimetry. The PAIs exhibit ...
