| l,3-DHSopropyl-4,5-dimethylimidazolium-2-N,N'-diisopropylamidinat, ein neuartiges Retain [1] 1,3-Diisopropyl-4,5-dimethylimidazolium-2-N,N'-diisopropylamidinate, a Novel Betaine [1]  | | | | Abstract
| The imidazolium-2-amidinate 6 is obtained from the reaction of 2,3-dihydro-1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene (4) with diisopropylcarbodiimide (5) as stable solid. Overcrow ding causes a lowered symmetry of the amidinate fragment indicated both by structural and NMR data. The strongly basic properties of 6 allow facile protonation with HC1 to the cationic amidine derivatives 7 and 8 . The ketoamidine 10 is formed by a ring opening reaction of 6 with water. I he X-ray structures of 6 and 10 are reported | | | |
