When an organo-magnesium halide is reacted with an excess of trichlorosilane, a mixture of products results according to the equations. If phenyl magnesium bromide is used, a mixture of high boiling products results, the highest boiling point of which is approximately 250° at 14mm. pressure. If ethyl magnesium bromide is used, it may be shown that, making certain assumptions and under the conditions of the experiment, if ethyl magnesium bromide is added to the trichlorosilane, monosubstitution is promoted, whereas if the trichlorosilane is added to the ethyl magnesium bromide, polysubstitution is promoted.
