Chained up : The π conjugation along B‐C‐N chains and a shift into a deep valence area of σ molecular orbitals (HOMO−6) are the reasons for the high stability of the dimer [B(NHC)] 2 (NHC=N‐heterocyclic carbene). The cyclic compounds [B(NHC)] n (see selected MOs for n =6) exhibit structural and aromatic features similar to the corresponding hydrocarbons (CH) n .
