Aromatic amines amides

Hydroperoxides have been obtained from the autoxidation of alkanes, aralkanes, alkenes, ketones, enols, hydrazones, aromatic amines, amides, ethers, acetals, alcohols, and organomineral compounds, eg, Grignard reagents (10,45). In autoxidations involving hydrazones, double-bond migration occurs with the formation of hydroperoxy—azo compounds via free-radical chain processes (10,59) (eq. 20).

The mercuration of 1,5-hexadiene in the presence of aromatic amines, amides or carbamates is a suitable method for the preparation of 2,5-disubstituted pyrrolidines. The stereochemical outcome of this cyclization is strongly determined by the reaction conditions, 1,3-asymmetric induction depends on whether kinetic or thermodynamic control takes place. When mercury(II) acetate was allowed to react at — 20 °C in tetrahydrofuran with 1,5-hexadiene in the presence of an excess of arylamine (kinetic control), tra s-.V-substituted 2,5-dimethylpyrro-lidines 7 were the major product after reductive cleavage of the C —Hg bond88,89. 

Many useful titrations can be performed in glacial acetic acid, which is used widely for the titration of aromatic amines, amides, ureas, and other weak nitrogen bases. Direct titration of most amino acids with a standard acid can be performed in glacial acetic acid.
