found to be an excellent ligand for copper-catalyzed N-arylation of azoles and amides with aryl halides under mild conditions. The reaction took place at 82 °C in MeCN with broad functional-group compatibility. A combination of the ligand and CuI proved to be an efficient catalytic system to promote the coupling reactions of aryl halides with azoles and amides.

benzamides promoted by potassium carbonate in the presence of DMEDA was developed. The reaction was carried out without addition of any transition-metal catalyst to afford a variety of N-arylated products in moderate to good yields (up to 97%). A practical and efficient method for N-arylation of benzamides promoted by potassium carbonate in the presence of DMEDA was developed. The reaction was carried out
The Synthesis of<i>N</i>-Arylated Amides<i>via</i>Copper(II) Triflate- Catalyzed Direct Oxygenation and<i>N</i>-Arylation of Benzylamines with Aryl Iodides
An efficient approach for the synthesis of N-arylated amides by copper(II) triflate-catalyzed direct oxygenation and N-arylation reaction of benzylamines with aryl iodides is reported. Various benzylamines and aryl iodides can participate in the reaction, providing a series of N-arylated amides in moderate to good yields.
An efficient iron-catalyzed synthesis of N-aryl amides from N‑methoxy amides and arylboronic acids is developed. FeCl3 is used as the sole catalyst for the cross-coupling reaction between N‑methoxy amides and arylboronic acids without any other additives, and the corresponding N-aryl amides are obtained in moderate to excellent yields.

The occurrence of 3D isostructurality in six halogensubstituted N-benzoyl-N-phenylbenzamides has been reported and this feature has been quantitatively analyzed in this study. 4-fluoro-N-(4-fluorobenzoyl) N-(fluorphenyl)benzamide (1) was observed to be isostructural with 2-fluoro-N-(2fluorobenzoyl) N-(4-fluorophenyl)benzamide (7), N-(4-bromophenyI)-2-fluoro-N-(2-fluorobenzoyl) benzamide (8) and 2
