Oxidation of primary aromatic amines under irradiation with ultrasound and/or microwaves

The oxidation of primary aromatic amines, p-methylaniline, p-ethylaniline and p-chloroaniline to the corresponding azo- and azoxy-compounds has been observed in ultrasound and/or microwaves systems. The individual irradiation of microwaves and its simultaneous irradiation with ultrasound obviously elevate the conversion of amines, as compared with the individual irradiation of ultrasound and the heating in a plain water bath. However, the formation of formamidine resulted in poor selectivity toward azo and azoxy products in the presence of dimethylformamide (DMF). Copyright Taylor & Francis Group, LLC.

A facile and efficient one-pot synthesis of 1,3-disubstituted pyridin-2(1H)-ones is developed via a novel cascade reaction of readily available α-hydroxy-α-carbamoyl ketene S,S-acetals under Vilsmeier conditions (DMF/POCl3), and a mechanism of this domino reaction is proposed.

STEREOSPECIFIC FORMATION OF AMIDINES BY 1,1-ADDITION OF AMINES TO ISOCYANIDES
Hegarty, Anthony F.,Chandler, Anne
, p. 885 - 888 (2007/10/02)
Addition of secondary amines to isonitriles in the presence of AgCl at low temperature gives isolable but thermodynamically unstable Z-amidines; only the more stable 6E undergoes ring expansion to the imidazoline 7.
