Description:
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 R 2 Si = Si( R )–Si(Cl) R 2 ( 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 Et 2 O solvate of the corresponding disilenide.
