Regioselective side-chain nitration of polymethylbenzenes directed by an acyl function and its application to the synthesis of polysubstituted phthalic acid derivatives
In the presence of diphosphorus tetraiodide, a variety of weak carboxylic acids readily react with amines to form the corresponding amides in high yields.
在磷酸四碘化物存在下,各种弱羧酸容易与胺反应,生成相应的酰胺,并且产率很高。
