The stub should be expanded to consider at least two commercial uses. At the N2 bond diazo compounds readilly combine, or couple, to form new compounds. Many of these are colored. By choice the diazo was water soluble, the dye is water insoluble. This was a 19th century method of fast dying fabrics. Many diazo compounds are light sensitive at 350 to 450 nm. The bond is broken and the tar produced does not couple. This was a the basis of a copying process that replaced blueprints. This process is currently in diminishing use.
I worked in the reprographic industry, as a physicist, from 1954 to 1982. I will help page preparation on this, but it has to be led by a chemist.
- Hi Regnim, why don't you just start the edit you intend to make, there are plenty of chemists around keeping an eye on this page who will glad to be of assistance V8rik 22:20, 22 December 2005 (UTC)

azo / diazo
- Can someone clear up the relationship between the terms 'diazo' and azo compound? And does the 'di' in 'diazo' mean anything. Is there a different 'azo' functional group? ike9898 14:53, 28 July 2006 (UTC)
- diazo is the functional group R=N(+)=N(-) e.g. CH2=N2. azo (which is the same as diimide) is the functional group (-)N=N(-). In inorganic chemistry you have: amide (R2N(-)) and imide (RN(2-)) and boths are something completly different in organic chemistry.
Resonance sturucture is missing the 1,3-dipole
Hazard of the diazo compound
Should there be information about the potential hazards of diazo compounds? My organic chemistry professor was just talking about it being really prone to explosion and hazardous to human health if inhaled, but I'm not too sure I have grasped the whole idea enough to explain it.

The figure shows a diazo transfer but the reagent is definitely not tosyl azide...and I am skeptical that a diazo transfer would even occur using phenyl azide. Perhaps a new figure should be made. — Preceding unsigned comment added by 126.96.36.199 (talk) 03:33, 15 October 2011 (UTC)
