• The first anionic N-heterocyclic dicarbene, polymeric [:C{[N(2,6-Pri 2C6H3)]2CHCLi(THF)}] n 1, containing both normal (C2) and abnormal carbene (C4) centers in the same five-membered imidazole ring (III), has been prepared by lithiation of the imidazole monocarbene, :C{N(2,6-Pri 2C6H3)CH}2. The dicarbene nature of 1 was unambiguously demonstrated by the formation of the group 13 Lewis acid adducts (THF)2Li:C{[N(2,6-Pri 2C6H3)]2CHC(LA)}, where LA = AlMe3 [2·(THF) 2 ] and BEt3 [3·(THF) 2 ].
