Chemical Abstracts names, amines

Chemical Abstracts names amines as alkanamines (and henzenamines), alkyl substituents on the nitrogen being designated as A-alkyl. Another system is based on the label aminoalkane. Common names are based on the label aUtylamine. 

Common names of the compounds arc used throughout this volume. Preparations appear in the alphabetical order of common names of the compound or names of the synthetic procedures. The Chemical Abstracts indexing name for each title compound, if it differs from the common name, is given as a subtitle. Because of the major shift to new systematic nomenclature adopted by Chemical Abstracts in 1972, many common names used in the text are immediately followed by the bracketed, new names. Whenever two names are concurrently in use, the correct Chemical Abstracts name is adopted. The prefix n- is deleted from w-alkanes and w-alkyls. In the case of amines, both the common and systematic names are used, depending on which one the Editor-in-Chief feels is more appropriate. All reported dimensions are now expressed in Systeme International units.

Description Catecholamine is the name of a group of compounds that contain a catechol nucleus (a benzene ring with two adjacent hydroxyl substituents) and an amine group. This group includes the mammalian neurotransmitters or hormones, such as dopamine, norepinephrine, and epinephrine, and nonmammalian compounds such as octopa-mine. Each compound has its own synonyms.

Draw and name simple amines using the Chemical Abstracts, common, and I.U.P.A.C. nomenclature system. 

The nomenclature system that has gained great popularity is known as the Chemical Abstracts or CA system. This system has been approved for use by I.U.P.A.C. and will be presented here because it is logical and easy to use. In the CA system the final -e of the name of the parent compound is dropped, and the suffix -amine is added. Eor instance,...

Draw a diagram to illustrate your answer to Problem 16.17. Use the Chemical Abstracts system of nomenclature to name each of the following amines ... 

Recently, Chemical Abstracts (CA) introduced a system for naming amines that is rational and easy to use. In this system, amines are named as alkanamines. For example. 

Another way of naming amines is by the Chemical Abstracts system, in which the suffix -amine is used after the name of the longest alkane chain attached to the nitrogen. Primary and secondary amines are capable of forming hydrogen bonds with each other. The following example illustrates this ... 

The system for naming amines is confused by the variety of conunon names in the literamre. Probably the best way to name aliphatic amines is that used by Chemical Abstracts— that is, as alkanamines, in which the name of the alkane stem is modified by replacing the ending -e by -amine. The position of the functional group is indicated by a prefix designating the carbon atom to which it is attached, as in the alcohols (Section 8-1). 

In Summary There are several systems for naming amines. Chemical Abstracts uses names of the type alkanamine and benzenamine. Alternatives for alkanamine are the terms amino-alkane and alkylamine. The common name for benzenamine is aniline.
