Abstract

We report mild routes for the deposition of crystalline films of elemental tin via the formation and subsequent decomposition of unstable tin(II) hydrides. Specifically, we take advantage of efficient O^tBu/H metathesis involving Sn(II) alkoxide precursors and the hydride source pinacolborane (HBpin); related -N(SiMe₃)₂/H exchange also afforded elemental tin as a final (insoluble) product.
