ResumoThe stable stannanediyl 2 and the carbene-like species 1 react to give stannaefhene 3. The structure of 3 was established by NMR spectroscopy and by X-ray structure analysis. The very high-frequency 119Sn-NMR signal indicates that the C=Sn bond has strongly polar character (ylide form 3A). R1 = Si(CH3)3; R2 = C(CH3)3; R3 = CHR.
