Tris trimethylsilyl methylsilane

The syntheses of benzosilacyclopentenes have been tabulated (b-82MH2000). The pyrolysis of phenyl-substituted tris(trimethylsilyl)methylsilanes affords a novel route to 1,3-disilain-danes. The fluoride (101) decomposes with loss of trimethylfluorosilane, probably via a series of interconverting silaalkene intermediates, to give the three indanes (102)-(104)... [Pg.611]

Preparative Methods several methods for the preparation of bis[(trimethylsilyl)methyl]zinc have been reported. Addition of powdered anhydrous zinc(II) chloride to a solution of [(trimethylsilyl)methyl]magnesium chloride in diethyl ether at 0 °C and subsequent stirring for 4 days at room temperature affords the title compound in 90% yield after fractional distillation. A second route consists of the reaction of (iodomethyl)tri-methylsilane with zinc/copper couple (prepared by reduction of CuO with dihydrogen in the presence of zinc dust) at reflux for 3 h and affords the title compound in 56% yield. Bis[(trimethylsilyl)methyl]zinc can also be prepared quantitatively by reacting bis[(trimethylsilyl)methyl]mercury with an excess of zinc at ambient conditions. ... [Pg.76]
