Efficient Conversion of Thiols to S-Nitrosothiols with the 18-Crown-6 Complex of N2O4 as a New Nitrosating Agent
Abstract
Gaseous N2O4 reacts with 18-crown-6 to afford a stable ionic complex of NO+·18-crown-6·H(NO3)2–; this complex is an efficient nitrosating agent for the conversion of thiols to their corresponding S-nitrosothiols in different organic solvents.
