Synthesis, Characterization and Reactivity of a σ‐Donating Ni(0)‐Stabilized Silyliumylidene Ion

The synthesis of a silyliumylidene cation complex 2 stabilized by a Ni(0)‐based donating ligand is reported. Experimental and theoretical studies demonstrate that the highly electrophilic Si(II) center is stabilized by a dative Ni→Si σ‐interaction and π‐donations from the amino‐ and Ni‐moieties. Due...

description The synthesis of a silyliumylidene cation complex 2 stabilized by a Ni(0)‐based donating ligand is reported. Experimental and theoretical studies demonstrate that the highly electrophilic Si(II) center is stabilized by a dative Ni→Si σ‐interaction and π‐donations from the amino‐ and Ni‐moieties. Due to the energetically close frontier orbitals localized on the Si and Ni atoms, complex 2 presents a competitive reactivity at Si and Ni sites.
