WebApr 10, 2024 · Reduction of Fe causes an expansion of the Fe-O bond as the central Fe gaining electrons can explain this small expansion in 1st and 2nd shell distances (Table 5). The lack of change in coordination numbers or large change in distances (>0.02 Å) indicates this reduction happens to Fe without atoms leaving the phyllosilicate crystal lattice. WebNitro Reduction Common Conditions: H 2 + Pd/C Catalytic hydrogenation with palladium on carbon ( Pd/C) is often the method of choice for nitro reductions. Both aromatic and aliphatic nitro groups are reduced to amines. One drawback of H2 + Pd/C is its ability to react with a wide variety of other functionalities on a substrate.
