to the anion of 2-nitropropane, SN2 attack of the anion of 2-nitropropane on symmetrical disulphides, and SRN1reaction of 2-substituted-2-nitropropanes with thiolate anions. The α-nitrosulphides undergo SRN1 substitution with the anion of 2-nitropropane, and SRN1 substitution or redox reactions with thiolate anions. The electron spin resonance (e.s.r.) spectrum of the radical-anion of 1-methyl-1-nitroethyl

compound, is easy to prepare and stable as a solid, and was shown to be a useful functional group transforming agent in this report. Oxidative synthesis of symmetrical disulfides from thiols in the presence of compound 1 alone was performed in 58–100% yields. Furthermore, ESI-MS demonstrated that premixing of 1 and Ph3P yields the corresponding acyloxyphosphonium, which can acylate thiols to produce
