An Efficient Method for Production and Storage of Unstable S-Nitrosothiols Under Mild and Heterogeneous Condition with Sodium Nitrite and Oxalic Acid Dihydrate

Thiols can be readily converted to their corresponding nitrosothiols with a combination of oxalic acid and sodium nitrite in t-butanol at room temperature (26-30°C). The reaction mixture could be solidified with decreasing its temperature to, 15°C and was stored for several days without any destruction of the nitrosothiols.
