ACD/Name

Groups Containing Three or More Contiguous Nitrogen Atoms

Rule C-942

942.1 - Compounds derived by substitution from , , , , , or etc. The chain of nitrogen atoms is numbered consecutively from one end to the other. Double bonds are designated, and assigned lowest available numbers, as in the aliphatic series (Section A), and they have priority over substituents for lowest numbers. (For naming triazanes, etc., by the replacement method for open chains, see Subsection C-0.6).

Examples to Rule C-942.1

1-Methyltriazane

1-Methyl-3-propyltriazane

3-Methyltriazene

3-Methyl-1-tetrazene

942.2 - Alternatively, compounds containing the same radical R at each end of an -N=N-NH- group may be named by attaching the prefix "diazoamino-" to the name of the compound RH, the whole preceded by locants if necessary.

Examples to Rule C-942.2

Diazoaminobenzene

2,2'-Diazoaminonaphtalene

N-Methyldiazoaminobenzene

942.3 - When the compounds described in Rule C-942.1, are converted into radicals by loss of a terminal hydrogen atom the terminal "-ne" of their names is changed to "-no"; the point of attachment of the radical then has the locant 1.

Examples to Rule C-942.3

p-2-Triazenobenzoic acid

Ethyl tetrazanoacetate
