(a) reacting an aqueous solution of an amine with an anhydride previously dissolved in an anhydrous water miscible organic solvent, dissolved in an anhydrous water miscible organic solvent, and (b) reacting the intermediate obtained from the first reaction with an R f -thiol in the presence of...
2.5.3.5.1 The Polonovski reaction The Polonovski reaction occurs when an amine oxide reacts with an acylating agent.39 The accepted mechanism involves proton removal to give a nitrogen ylide which loses acetate (using acetic anhydride) which attacks the carbon adjacent to the nitrogen atom giving...
Question: explain why only one amine hydrogen which is get substituted by acetyl group eventhough acetate anhydride is used excessively in the reaction??

Amine oxide group-containing maleic anhydride (MA) copolymers, obtained by (a) reaction of at least 1 mol% of the anhydride groups in MA copolymers with diamines of formula (I), followed by (b) oxidation to form amine oxide groups attached by half-amide and/or imide groups of formula (...
The dissociation energy for the bond NH2CR3 is about 77.2 kcal/mol, and for the bond C2H5CR3 is about 76.9 kcal/mol. Because the two dissociation energies are so close, reaction (8.1.3) is a likely process. The CC bonds involving only primary or secondary carbons have slightly higher diss...
