3.8.1
Azo and Azoxy Compounds
Although a thoroughly consistent, systematic approach to the naming of
virtually all azo and azoxy compounds - compounds which have traditionally been treated very disparately - on the basis of the highly versatile
parent hydride name diazene has existed for some time, several customary older naming modes are still perpetuated in pretty confusing ways
(even by Chern. Abstr.!). These demand a more detailed discussion.
Undisputed are diazene names for derivatives containing hydrocarbon,
alkoxy, and comparable substituent groups or directly attached senior
functionalities.
