摘要：
A tale of two carbenes: Reaction of:C[N(2,6-iPr 2C 6H 3)CH] 2 (IPr) with Mn 3(mes) 6 (mes=2,4,6-trimethylphenyl) yielded the trigonal planar complex [Mn(IPr)(mes) 2]. Reduction of this species with potassium/graphite in THF afforded the polymeric dicarbene-bridged species K[{:C[N(2,6-iPr 2C 6H 3)] 2(CH)C} 2Mn(mes) (thf)] THF (see picture). The anionic moiety in this complex is the first reported example of a transition metal complex containing an N-heterocyclic dicarbene ligand. Gray C, blue N, red Mn.
