Hydrogen peroxide based oxidation of hydrazines using HBr catalyst

Azo compounds (RN = NR′) are an important class of organic molecules that find wide application in organic synthesis. Herein, we report an efficient, practical and metal-free oxidation of hydrazines (RNH-NHR’) to azo compounds using 5 mol% HBr and hydrogen peroxide as terminal oxidant. This new method has been demonstrated by 40 examples with excellent yields. In addition, we showcased two examples of the one-pot sequential reactions involving our hydrazine oxidation/hydrolysis/Heck reaction or Cu-catalyzed N-arylation with aryl boronic acid. The distinct advantages of this protocol include metal-free catalysis, waste prevention, and easy operation.

Palladium-Catalyzed Carbonylative Cyclization of Azoarenes

In this communication, we established an interesting palladium-catalyzed carbonylation protocol for the intramolecular cyclization of azoarenes. With Mo(CO)6 as the solid CO source and through C(sp2)?H bond activation, a series of azoarenes were transformed into the corresponding 2-arylindazolones in moderate to good yields. Notably, not only symmetrical azoarenes, but also unsymmetrical substrates underwent the reaction with excellent regioselectivity.

PREPARATION OF AZO COMPOUNDS WITH SOLID CATALYSTS

The present invention refers to a procedure for preparing azo compounds comprising a reaction between at least: one amine or polyamine, molecular oxygen, a catalyst comprising at least one support selected from at least a metal oxide of one of the elements of the groups 3, 4, 5, 6, 8, 9, 11 and 13, silica, an anionic laminar compound of hydrotalcite type or its derivatives, active carbon or an organic polymer. In addition, said catalyst may contain nanoparticles of gold.
