imines

https://doi.org/10.1351/goldbook.I02957
  1. Compounds having the structure $\ce{RN=CR2}$ ($\ce{R} = \ce{H}$, hydrocarbyl). Thus analogues of aldehydes or ketones, having NR doubly bonded to carbon; aldimines have the structure $\ce{RCH=NR}$, ketimines have the structure $\ce{R'2C=NR}$ ($\ce{R'} \neq \ce{H}$). Imines include azomethines and Schiff bases. Imine is used as a suffix in systematic nomenclature to denote the $\ce{C=NH}$ group excluding the carbon atom.
  2. An obsolete term for azacycloalkanes.
