A Tin Analogue of Propadiene with Cumulated C=Sn Double Bonds

Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

The synthesis, structure, and properties of a stable, linear 2-stannapropadiene are reported. The identical C=Sn bonds in this 2-stannapropadiene are the shortest hitherto reported C–Sn bonds. This 2-stannapropadiene features a 119Sn NMR signal at 507 ppm for the central tin atom, indicative of an unsaturated SnIV oxidation state. Treatment of this 2-stannapropadiene with SnCl2·dioxane resulted in the formation of a novel four-membered cyclic 1,1-dichloro-1,3-distannetane.
