aluminumAluminum mercury alloy is used as a chemical reagent to reduce compounds, such as the reduction of imines to amines,in this case mercury destroy aluminium oxide layer which protect aluminium to react with water.
alloyAlloy of aluminium and gallium which similar to above alloy make the aluminium more reactive by preventing it from forming an oxide layer.
inIn both cases mercury and gallium plays a same role of destroying oxide layer on aluminium to react with water but why can't gallium aluminium alloy reduce imines to amines like mercury aluminium alloy ?
