Jul 23, 2018 · Sodium dithionite Na2S2O4 (also called sodium hydrosulfite) is a flexible reducing agent that reduces and cleaves ArN=NAr bonds to give ArNH2. It is also good for ArNO2 to ArNH2 and reductions of enones to ketones. Further reading here 1

Feb 17, 2022 · I've recently come across the synthesis of 3-aminopthalhydrazine from 3-nitropthalhydrazine where the reducing agent used was sodium dithionite ($\ce{Na2S2O4}$). I wanted to know what the mechanism of this reaction …
