Reactions of stable 1,2‐dibromodisilenes (( E )‐Ar(Br)SiSi(Br)Ar) with N‐heterocyclic carbenes (NHC) afforded NHC–arylbromosilylene adducts or bromide salts of the corresponding bis‐NHC adducts of the formal arylsilyliumylidene cations ([ArSi:] + ). In some cases, an NHC was able to replace a bromide anion in the coordination sphere of the arylbromosilylene–NHC adduct.
