✦ Synopsis
Metal-solution interfacial phenomena occuring when magnesium is attacked by a halogen derivative are studied by KPS analysis of the state of the surface formed during this reaction.
Although many studies' deal with the mechanism of organomagnesium compound formation in solution, we are not aware of any concerning the physico-chemical phenomena occurring at the metal-solution interface when the metal is attacked by a halogen derivative. This is due to the fact that, generally, this type of attack does not cause an observable surface change that would allow this type of study to be conducted. In synthesizing I-adamantyl magnesium bromide* from Ibromoadamantane, we succeeded in obtaining, on the metal surface, a black layer with a thickness of up to 7 1-1. The elements present at different depths of the layer were detected and analyzed using XPS 3 and ion bombardment, 4 thereby establishing the relationship between the characteris-
