ABSTRACT:
The preparation of halosilanes having mixed-halogen substituents is described comprising providing an aryl-halo-silane having one more first halogens and one or more aryl groups, and substituting one or more of said aryl groups of said aryl-halo-silane with a second halogen having an atomic number greater than that of said first halogen.
