Novel methods for producing alpha-alkenylalkylsilanes by reacting alkenylhalosilanes and organoalkalimetalaluminates have been discovered. For example, vinyltrichlorosilane and sodium tetraheylaluminate can be reacted to produce alpha-alkenyltrihexylsilane.

Methods of producing alpha-alkenylalkylsilanes

New methods of producing phenylalkylsilanes having a desired ration of phenyldialkylsilanes to phenyltrialkylsilanes using effective control of temperature in the reaction of sodium trialkylaluminum and phenyltrihalosilanes are disclosed.

Method of preparation of phenylalkylsilanes

Improved silahydrocarbon mixtures comprising phenyltrialkylsilanes wherein the alkyl groups independently are hydrocarbon chains having from about 4 to about 20 carbon atoms, preferably each independent alkyl group differing from the other by no more than about 2 carbon atoms, are produced having unexpectedly good resistance to oxidation and having use in lubrication compositions.
