Triazene
From Wikipedia, the free encyclopedia
Not to be confused with triazine.
Triazene is the chemical compound NH2N=NH but it has also given name to the functional group consisting of an amine directly bonding to an azo group, i.e. with the linkage R2N-N=NR' where R and R' are substituents. The functional group is also called a diazoamino group (but only one of the two substituents R and R' may be hydrogen) because it is related to a diazo group.
A well known example is of a triazene is diphenyl derivative,[1] PhNH-N=NPh (m.p. 100 °C, CAS #136-35-6). It is prepared from phenyldiazonium salts and aniline in the presence of base:
- PhN2+ + PhNH2 → PhNHN=NPh + H+
