Abstract
Olefins and metal aluminum tetralkyls react with alkylhalosilanes to yield mixtures of tetraalkyls silanes which may be employed as functional fluids. For example, decene-1 and sodium aluminum tetraoctyl, NaAl(C.sub.8 H.sub.17).sub.4, react with methyltrichlorosilane. The mole ratio of sodium aluminum tetraalkyl to halosilane is from about 0.75:1.0, to about 1:1, and the ratio of olefin to the metal aluminate is selected to confer in the product mixture, the desired concentration of alkyl radicals derived from the olefin.
