Etymology Information

'imine' originates from German, specifically the word 'Imin', where the combining form 'imino-' was used in organic chemistry to denote a nitrogen doubly bonded to carbon.

Historical Evolution

'imine' was coined in 19th-century German chemical literature from the combining form 'imino-' and the suffix '-ine', and the term was later adopted into English scientific usage as 'imine'.

Meaning Changes

Initially used broadly for nitrogen-containing double-bonded species, it came to denote specifically compounds with a carbon–nitrogen double bond (C=N), commonly called Schiff bases.
