Abstract

Abstract: 1, l-Dibromo-and 1, l-diiodo-2, 3, 4, 5-tetraphenylstannacyclopentadienes (dibromo- and diiodostannoles) formed from controlled phenyltin cleavage of hexaphenylstannole by elemental bromine and iodine, respectively, undergo conventional alkylation by methyllithium to form the expected 1, l-dimethylstannole, but treatment with excess lithium or thallium cyclopentadiene yields cubic crystals whose analytical data agree with the ...
