The 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 119 Sn‐NMR signal indicates that the C=Sn bond has strongly polar character (ylide form 3A ). R 1 = Si(CH 3 ) 3 ; R 2 = C(CH 3 ) 3 ; R 3 = CHR 2 1 .
