Spectroscopic evidence for donor-induced formation of nitrosonium in acidified solutions of alkyl nitrites

Abstract

The "donor-induced" generation of nitrosonium cation in acidified solutions of alkyl nitrites in dichloromethane is demonstrated spectroscopically. Electron-rich organic molecules, including polymethylbenzenes and thioethers, affect the donor-induced release of nitrosonium as the corresponding electron donor-acceptor complex [donor, NO+]. These complexes are spectrally identified using a combination of UV-vis and IR spectroscopy. The almost quantitative formation of the [donor, NO+] EDA complex with hexamethylbenzene and butyl sulfide as donors is verified with UV-vis spectroscopy.
