WebApr 2, 2024 · By combining the use of a miscible organic solvent with saturated sodium bisulfite, aldehydes and reactive ketones can be successfully transformed into charged bisulfite adducts that can then be separated from other organic components of a mixture by the introduction of an immiscible organic layer. Web• The reaction uses H2 and a precious metal catalyst. • The catalysts is not soluble in the reaction media, thus this process is referred to as a heterogenous catalysis. • The catalyst assists in breaking the p-bond of the alkene and the H-H s-bond. • The reaction takes places on the surface of the catalyst. Thus, the rate
