iminen.

Brit.

/ˈɪmiːn/,

/ɪˈmiːn/, U.S.

/ˈɪˌmin/,

/ˈɪmᵻn/

Etymology: < German imin (A. Ladenburg 1883, in Berichte der Deutsch. Chem. Ges. 16 1150), formed by altering amin amine n. (compare imide n., amide n.).

Chemistry.

Any compound containing the group NH (or the substituted form NR) attached to one carbon atom that forms part of a non-acidic organic group, or containing it in symmetrical compounds of the type R·NH·R; also applied (unsystematically) to other compounds in which it is attached to two carbon atoms (strictly, atoms forming part of non-acidic groups), esp. when they are part of a ring (as in ethylene imine, (CH₂)₂NH).
