N. Iranpoor et al., DINITROGEN TETROXIDE COPPER NITRATE COMPLEX [CU(NO3)(2).N2O4] AS A NEW NITROSATING AGENT FOR CATALYTIC COUPLING OF THIOLS VIA THIONITRITE, Synthetic communications, 28(2), 1998, pp. 367-375
A catalytic and efficient oxidative coupling of thiols to disulfides i
s described using Cu(NO3)(2) . N2O4 as a new and efficient nitrosating
agent in acetone at room temperature. The reaction is shown to occur
immediately through the intermediacy of a thionitrite.
