A stannane, which is simple to prepare, was successfully used in standard radical reactions as replacement of Bu3SnH and Ph3SnH. The tin-containing byproducts are removed by mild hydrolysis and extraction with aqueous NaHCO3. The performance of this new reagent was tested for reactions involving halides, selenides, Barton-McCombie deoxygenation and enyne cyclization.
