The first N-heterocyclic carbene (NHC) stabilized silyl-substituted chlorosilylene () was isolated via selective dehydrochlorination by NHC from silyl-based Si(IV) precursor BuSiSiHCl. Compound can form an iron chlorosilylene complex () with an iron carbonyl dimer and undergoes chloride/hydride metathesis to yield a stable NHC-silylene hydride borane adduct (). Upon treatment with additional NHC, chlorosilylene was converted into silyl-substituted silyliumylidene ions ().
