Diazooxides
Term · Chemistry · MLC-T-CHM-003148
Diazocyclohexadienones, also called diazophenols, made by diazotizing a primary aromatic amine that carries a hydroxy group ortho or para to the amino group. They can equally be written as dipolar diazonio phenoxides, a zwitterion with a diazonium group and a phenoxide oxygen on the same ring. The ortho-quinone diazides are stable enough to handle, and on irradiation they lose dinitrogen and undergo the Wolff rearrangement, the basis of diazonaphthoquinone photoresists.
