Olefins and metal aluminum tetraalkyls react with alkylhalosilanes to yield mixtures of tetraalkyl silanes which may be employed as functional fluids. For example, decene-1 and sodium aluminum tetraoctyl, NaAl(C8H17)4, react with dialkyldichlorosilane. The mole ratio of sodium aluminum tetraalkyl to halosilane in from about 0.5:1.0 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.
