Vinyl-Functionalized Janus Ring Siloxane: Potential Precursors to Hybrid Functional Materials.

ABSTRACT: A vinyl-functionalized all-cis-tetrasiloxycyclotetrasiloxane [ViSi(OSiMe₂H)O]₄ (Vi = vinyl group) Janus precursor was prepared from potassium cyclotetrasiloxane silanolate. The Janus precursor was selectively modified at its dimethylhydrosilyl groups [-SiMe₂H] via the Piers-Rubinsztajn reaction to obtain a family of new tetravinyl-substituted Janus rings [ViSi(OR')O]₄ containing various functional groups in moderate yields. Remarkably, the tetravinyl groups on the structure remained intact after modification by the Piers-Rubinsztajn reaction. Since these synthesized compounds possess multiple functional groups (up to eight per molecule), they are potential precursors for advanced hybrid organic-inorganic functional materials.
