Probing the Reactivity of a Stable Silene Using Muonium

Taking the silenic route: Addition of a hydrogen atom analogue, muonium (Mu), to stable silene 1 gives rise to two distinct radical species, 1‐CMu and 1‐SiMu, allowing the relative reactivity of silenic carbon and silicon atoms to be probed. The former is the first reported example of a muoniated si...

Description
Summary:Taking the silenic route: Addition of a hydrogen atom analogue, muonium (Mu), to stable silene 1 gives rise to two distinct radical species, 1‐CMu and 1‐SiMu, allowing the relative reactivity of silenic carbon and silicon atoms to be probed. The former is the first reported example of a muoniated silyl radical. The radical species are detected by muon spin rotation and resonance spectroscopy (μSR).
