Abstract
Dichlorosilane and phenyltrichlorosilane are prepared in good yields by reacting trichlorosilane and diphenyldichlorosilane in the presence of aluminium chloride, as catalyst, and a small proportion of a co-catalyst which is selected from hydrochloric acid and alumina and mixtures thereof, isolating the dichlorosilane from the reaction medium as it is formed and isolating the phenyltrichlorosilane obtained at the end of the reaction.
