silanes in the pressure experiments should have resulted in much lower percentages or even none of the chlorofluorosilanes, as was the case with carbon tetrafluoride. Therefore, it may be concluded that the chlorofluorosilanes apparently undergo extensive thermal disproportionation a t 500”, whereas a t lower temperatures, in the presence of aluminum chloride, no disproportionation was evident.?’ The disproportionation of the chlorofluorogermanes has been reported to take place even at -76”’ and under the conditions of the reactioiis einployed in this work, the existence of these compounds, if formed, would be transitory. Hence,
