New Silicon and Tin Containing Ring and Cage Compounds - Syntheses and Reactivity

Abstract

The syntheses of new stannyloligosilanes starting from dichlorodi-organostannanes (R₂SnCl₂) and α,ω-difluoromethyloligosilanes with magnesium are described. Depending on the molar ratio of reactants and substituents R, cyclic or acyclic compounds are formed. X-ray structure of 4b and reactivity of the cyclic stannylsilanes are also reported.
