The insertion reaction of trimethylstannyllithium into the oxirane, oxetane, thiirane, and thietane rings are reported.Regio-isomerically pure β- and γ-trimethylstannyl alcohols and thiols have been obtained from monoalkyl- and aryl-oxyranes and monoalkyl- and aryl-oxetanes, whereas reactions involving polysubstituted oxiranes resulted in a loss of regioselectivity.Ring opening of sulphurated heterocycles let to previously unreported β- and γ-trimethylstannyl thiols.The title reaction allows also the preparation of differently functionalised organostannanes which can be considered as versatile precursors of polyfunctional molecules.
