|Section2= |Section3= }} 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 imidazoline (dihydroimidazole). 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. Unsubstituted imidazolidines are not stable compounds and are prone to rapid decomposition. The first unsubstituted imidazolidine synthesis was reported in 1952 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Imidazolidine」の詳細全文を読む スポンサード リンク
