Abstract
Thermolysis of dibutyl(2-ethoxyethyl)stannane (4) in heptane at 150 de grees C quantitatively provides the perbutylated cyclopolystannanes (B u(2)Sn)(5) (1) and (Bu(2)Sn)(6) (2). Trapping experiments reveal that this formal reductive-elimination process proceeds in a step-wise mann er, involving the generation of a trivalent tin. intermediate that the n undergoes an. unprecedented beta-elimination reaction.
