Specific Classes of Compounds

R-5.6.6 Nitrogenous derivatives of carbonyl compounds

R-5.6.6.1 Oximes. Compounds having the general structure or are called generically "oximes" and have been further classified as "aldoximes" and "ketoximes", respectively. They are named according to the principles of functional class nomenclature by placing the class name "oxime" as a separate word after the name of the aldehyde RCHO or the ketone , respectively; or substitutively by use of the prefix "hydroxyimino-" attached to the name of a parent hydride or parent substituent prefix. Compounds containing the group may be named as O-substituted oximes or as alkoxy-substituted imines.

Examples to R-5.6.6.1

.

R-5.6.6.2 Hydrazones. Compounds having the general structure or are called "hydrazones" generically and are named according to functional class nomenclature by placing the class name "hydrazone" as a separate word following the name of the corresponding aldehyde or ketone, or substitutively by means of the prefix "hydrazono-" attached to the name of an appropriate parent hydride or parent substitutive prefix.

Examples to R-5.6.6.2

R-5.6.6.3 Azines. Compounds having the general structure or are called "azines" generically and are named substitutively as derivatives of diazane or as an assembly of identical units using the prefix "azino-". According to functional class nomenclature, they may be named by adding the class name "azine" as a separate word after the name of the corresponding aldehyde or ketone.

Examples to R-5.6.6.3

Compounds having the general structure (RR') are named as "ylidenehydrazones" (see R-5.6.6.2) of the preferred carbonyl compound or by using the prefix "hydrazono-".

Examples to R-5.6.6.3

R-5.6.6.4 Other nitrogen derivatives of carbonyl compounds. Derivatives of semicarbazide

of the types and may be named substitutively by using the functional parent compound name "semicarbazide", or the prefix name "semicarbazono-", or according to principles of functional class nomenclature, by adding the class name "semicarbazone" as a separate word after the name of the aldehyde RCHO or ketone . Chalcogen analogues are named in the same way on the basis of functional parent compound names such as "selenosemicarbazide" and prefix names such as "thiosemicarbazono-", or functional class names such as "thiosemicarbazone".

Examples to R-5.6.6.4

Other derivatives of semicarbazide, and derivatives of carbonohydrazide, , carbazone, , and their chalcogen analogues may be named substitutively using these functional parent compound names and prefix names such as "semicarbazido-", "thiocarbonohydrazido-" and "carbazono-". These prefix names describe a substittuent derived from the appropriate functional parent compound names by loss of one hydrogen atom from position "1" only.
