Semitrivial name

Semitrivial names. These are names that are derived by appending a systematically derived operator to a trivial parent. Examples are 8-(l,l-dimethylallyl)confusameline and A-cyano-i ec-pseudostrychnine. In general, such names should be avoided because of the possibilities for confusion, especially when there is a structure revision or where there is more than one numbering scheme in use for the parent skeleton. Trivial names should be preferred. 

The following oligosaccharides were designated by their trivial and semitrivial names, and the corresponding abbreviations have been used ... 

Semisystematic == semitrivial name. A name of which only a part is used in a systematic sense methane, butene, calciferol Most names in organic chemistry belong to this class many are often spoken of loosely and incorrectly as simply trivial . 

Most entries are headed by a systematic name but in the case of very well known reagents the trivial name is preferred. Care has been taken to incorporate as many helpful synonyms as possible, including trivial and semitrivial names, generic names and tradenames (including Colour Index names). 

A considerable number of trivial or semitrivial (traditional) names have been retained hy HJPAC for compelling practical reasons the approved ones are available. A very brief selection is shown in Table 2. Other contributions to organic nomenclature are available. 

Persistence of trivial and semitrivial (or semisystematic) names—e.g., nitrotoluidine, aminocresol, etc.—which, though convenient, are not systematic and may be confusing, as, for example, the nitroanisidines, where o-nitro-p-anisidine is an ambiguous form.
