Imidazolidine is a heterocyclic compound formally derived by the addition of four hydrogen atoms to imidazole. The intermediate, resulting from the addition of only two hydrogen atoms is called dihydroimidazole (imidazoline). The connection of imidazolidine to related compounds is indicated in the Figure.

Formally, removal of the two hydrogens at carbon 2 (between the two nitrogens) would yield the carbene dihydroimidazol-2-ylidene. Derivatives of the latter comprise an important class of persistent carbenes.[1]
