Notes:
Ga, Tl, Sn, Pb, As, Sb, Bi, Cd, and Hg chlorides react with magnesium anthracene · 3 THF (MgA), anthracene-activated magnesium, or “active magnesium” (Mg*) in THF, generating the respective Mg intermetallics in a nanocrystalline or amorphous state (Eqs. 1-3). Mg intermetallics accessible through the wet-chemical route can be exploited by metathetical exchange reactions for the preparation of other, highly active intermetallics and alloys; EXAFS investigation of X-ray amorphous Cu-Sn and Pd-Pb solids thus prepared (Eqs. 13 and 14) shows that they are true bimetallic alloys (solid solutions).
