Tris silane with phenyl radical

In the simplest application of this concept, Chatgilialoglu and Curran carried out allylation reactions with allyl phenyl sulfones in the presence of tris(trimethylsilyl)-silane [58]. These reactions are analogous to the tin-mediated reactions previously discussed however, tris(trimethylsilyl)silane is used instead of tributyltin hydride or hexabutylditin for propagating the radical chain. The yields in these reactions ranged from moderate to good. 

Allyl[tris(trimethylsilyl)]silanes. These valuable synthetic reagents are prepared by free-radical substitution of allyl phenyl sulfides with (MejSiljSiH. They can be used as radical-based allylating agents.
