Unsaturated silicon compounds are valuable building blocks for the synthesis of molecules with novel silicon-based structural motifs with potential applications in materials chemistry. The difficulties associated with the transfer of the Si=Si moiety to promising substrates can be explained by the lack of suitably functionalized derivatives. Herein we report the synthesis and full characterization of the first homoleptic trisilaallyl chloride R2Si = Si(R)-Si(Cl)R2(R = 2, 4,6-triisopropylphenyl) by an unprecedented nucleophilic substitution at a central silicon atom under retention of an adjacent Si=Si double bond. Attempts to reductively generate the corresponding allylic anion led to the cleavage of the Si-Si single bond and isolation of the Et2O solvate of the corresponding disilenide.

Si=Si activation: Reversible formation of a donor-acceptor complex between an N-heterocyclic carbene and a cyclotrisilene with carbon-based substituents shifts the electron density of the double bond and thus induces strong polarization, as shown by the significantly pyramidal tricoordinate silicon atom.
