Stannane decomposes slowly at room temperature to give metallic tin and hydrogen and ignites on contact with air.
The use of chiral electrophiles is common, and can provide " double stereocontrol " if the stannane is also chiral.
In the total synthesis of rocaglamide, epoxidation of a vinyl alkoxyallenyl stannane likewise generates a pentadienyl cation via ring opening of the resultant epoxide.
Early studies of PbH 4 revealed that the molecule is unstable as compared to its lighter congeners ( silane, germane, and stannane ).
"' Allylic stannane addition "'reactions comprise the nucleophilic addition of an allyl-, allenyl-, or propargylstannane to an aldehyde, imine, or, in rare cases, a ketone.
Stannane, a strong reducing agent slowly decomposes at room temperature to tin and hydrogen gas, and is decomposed by concentrated aqueous acids or alkalis; distannane, Sn 2 H 6 is still more unstable and longer stannanes are unknown.
This cycle is not limited to vinyl compounds, in the Sonogashira coupling one of the reactants is an alkyne and in the Suzuki coupling the alkene is replaced by an aryl boronic acid and in the Stille reaction by an aryl stannane.
Its properties are somewhat distinct from the rest of the hydrogen chalcogenides, since polonium is a metal while the other chalcogens are not, and hence this compound is intermediate between a normal hydrogen chalcogenide or hydrogen halide such as hydrogen chloride, and a metal hydride like stannane.
