Tris[bis(trimethylsilyl)methyl]tin(<scp>III</scp>), R₃Sn·: an unusually stable stannyl radical, from photolysis of R₂Sn

Abstract

Photolysis of R2Sn [R =(Me3Si)2CH] with visible light in benzene at ambient temperature yields the stable radical R3Sn·, which has an e.s.r. solution spectrum showing coupling with the methine protons and 119Sn and 117Sn nuclei.
