Abstract

Hydrido substituted stannasilanes of the type Z-SnR₂-Si(H)R′₂ or (R′₂Si(H))₂SnR₂ (Z=H, Me, Ph; R, R′=alkyl, Ph) are accessible by reaction of either alkali metal stannides (MSn(Z)R₂; M=Li, Na) with halogen substituted silanes (X-Si(H)R′₂; X=F, Cl) or chlorostannanes (R₂SnCl₂, Ph₃SnCl) and fluorosilanes (F-Si(H)R′₂) in the presence of magnesium. Stannasilanes with halogen substituents at the silicon as well as the tin atom are formed by treatment of the hydrido substituted stannasilanes with CHCl₃ or CCl₄. The hydrido substituted stannasilanes decompose in contact with air to distannanes and siloxanes or to the linear (^tBu₂Sn(-O-^tBu₂Si-OH) ₂) and cyclic ((-^tBu₂Sn-O-ⁱPr₂Si-O-) ₂) stannasiloxanes.
