Catalytic Method for the Conversion of Silanes to Stannanes

摘要

The transformation of alkynyl-, allyl-, and benzyltrimethylsilanes to thecorresponding tributylstannanes is reported. The reaction is initiated by the addition of tetrabutylammonium fluoride to a mixture of the silane and bis(tributyltin)oxide in tetrahydrofuran. The stannanes are isolated in approx. quantitative yields after removal of the volatile bis(trimethylsilyl)oxide in vacuo. Silane, Stannane, Catalysis.
