Abstract
Silahydrocarbons having the formula RSiR'.sub.3 are prepared by a three step process. In the first step in a preferred embodiment, sodium, aluminum, hydrogen and olefin (corresponding to the radical R') are reacted in the presence of a triorganoaluminum catalyst. In a second step, fresh catalyst is added and reaction continued. In a third step, the product of the second step is reacted with a trihaloalkylsilane to produce the RSiR'.sub.3 product. Such products are useful as functional fluids.
