A process for preparing functionalized alkyllithium compounds comprising reacting a fine particle size lithium metal of not more than 300 microns average particle size with an organosiloxyalkyl halide of the formula R<1>R<2>R<3>SiORX wherein R<1>, R<2> and R<3> are independently selected from alkyl groups containing 1 to 10 carbon atoms and aryl groups containing 6 to 10 carbon atoms, R is selected from alkyl groups containing 1 to 8 carbon atoms either straight chain or substituted by alkyl or aryl groups, X is selected from chlorine or bromine, the reaction temperature is above 50 DEG C, the reaction medium is a hydrocarbon solvent and the reaction is conducted in an inert atmosphere.
