Vinyl-Functionalized Janus Ring Siloxane: Potential Precursors to Hybrid Functional Materials
A vinyl-functionalized all-<i>cis</i>-tetrasiloxycyclotetrasiloxane [ViSi(OSiMe<sub>2</sub>H)O]<sub>4</sub> (Vi = vinyl group) Janus precursor was prepared from potassium cyclotetrasiloxane silanolate. The Janus precursor was selectively modified at its dimethylhy...

| description | A vinyl-functionalized all-<i>cis</i>-tetrasiloxycyclotetrasiloxane [ViSi(OSiMe<sub>2</sub>H)O]<sub>4</sub> (Vi = vinyl group) Janus precursor was prepared from potassium cyclotetrasiloxane silanolate. The Janus precursor was selectively modified at its dimethylhydrosilyl groups [–SiMe<sub>2</sub>H] via the Piers–Rubinsztajn reaction to obtain a family of new tetravinyl-substituted Janus rings [ViSi(OR’)O]<sub>4</sub> 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. |
