WebDithionic acid is diprotic and salts called dithionates are known. No acid salts (i.e.: one proton lost) have been discovered. All dithionates are readily soluble in water. [2] They are mild oxidizing and mild reducing agents. The shape of the dithionate ion is like ethane, but two SO 3 groups adopt an almost eclipsed conformation. WebSodium dithionite in an aqueous alkaline solution was used for selective reductions of the nitro group of dihydrotriazolotriazine 162.Partial hydrogenolysis of the methylsulfanyl substituent was observed with catalytic hydrogenation. 24 In contrast, reduction of 3-nitro[1,2,4]triazolo[5,1-c][1,2,4]triazin-4-amines 164 was carried out via catalytic …
