- Convergent Paired Electrochemical Synthesis of Azoxy and Azo Compounds: An Insight into the Reaction Mechanism
-
A convergent paired electrochemical method was developed for the synthesis of azoxy and azo compounds starting from the corresponding nitroarenes. We propose a unique mechanism for electrosynthesis of azoxy and azo compounds. We find that both anodic and cathodic reactions are responsible for the synthesis of these compounds. The synthesis of azoxy and azo derivatives have been successfully performed in an undivided cell, using carbon rod electrodes, by constant current electrolysis at room temperature.

- Synthesis of 2-Aryl-2 H-benzotrizoles from azobenzenes and N-sulfonyl azides through sequential rhodium-catalyzed amidation and oxidation in one pot
-
An efficient synthetic method of 2-aryl-2H-benzotriazoles from nonprefunctionalized azobenzenes and N-sulfonyl azides via sequential Rh-catalyzed amidation (C-N bond formation) and oxidation (N-N bond formation) with PhI(OAc)2 in one pot is reported.

- CONTROL OF THE THERMAL CIS TO TRANS ISOMERIZATIONS OF AZOBENZENE AND THIOINDIGO DERIVATIVES BY THE FORMATION OF SUPRAMOLECULAR H-BONDED ASSEMBLIES
-
2,3-Bis(aminocyclohexyl)-6-methoxy-1,3,5-triazine (1a) forms intermolecular H-bonded complexes with 3,3'-diacetyl-cis-azobenzene (4b) and 6,6'-diethoxy-cis-thioindogo (5b), (association constants K=4.9*104 and 3.5*105 l mol-1, respectvively).The thermal cis->trans isomerization of 4b and 5b to 3,3'-diacetyl-trans-azobenzene (4a), and 6,6'-diethoxy-trans-thioindigo (5a), is inhibited in the intermolecular complex 1a-4b and 1a-5b.Molecular mechanics calculations support the formation of the intermolecular H-bonded complexes between 1a and 4b or 5b.

- Effects of the Hydrogen-bonded Interactions on the Thermal cis to trans Isomerization of 3,3'-Diacetylazobenzene
-
The thermal isomerization of 3,3'-diacetyl-cis-azobenzene 1b is retarded in the presence of 2,4-bis(cyclohexylamino)-6-methoxy-1,3,5-triazine due to the formation of an intermolecular hydrogen-bonded assembly.
