IN this very concise treatise the author has summarized the history of the industrially important diazo-compounds since their earliest recognition by Peter Gries in 1858 until the present time.

The diazo radical intermediate ([Ar-N 2] ) can ... with phenols or other nucleophiles to generate the desired azo compounds.

Breakthrough in N2 activation! This study unveils an electron catalysis strategy that directly converts N2 into azo compounds under mild conditions—a game-changer for nitrogen fixation. By harnessing ...

The synthesis of azo compounds (R 1-N=N-R 2) poses an even greater challenge. Traditional methods involve multiple steps—oxidation of ammonia, nitrite preparation, and subsequent azo coupling ...
