| Research Abstract |
A persistent tri(silyl)silyl radical, bis(triisopropylsilyl)[phenyl(diisopropyl)silyl]silyl radical was generated by the reduction of the corresponding fluorosilane with sodium. According to EPR spectroscopy, spin delocalized on not only unsaturated silicon but also phenyl group.
An isolable diakylphosphinyl radical was successfully synthesized as a yellow crystalline solid and found to be monomeric both in solution and in the solid state. The spin density of the phosphinyl radical is almost localized on the 3p orbital of the dicoordinated phosphorus atom. Distinct electronic transition from nonbonding electron pair orbital to singly occupied 3p orbital on the phosphorus atom of the isolated phosphinyl radical was observed at 445 nm in solution. The reactivity of thus obtained phosphinyl radical has been investigated.
