Spectra and structure of sulfonium C-dinitro ylides

Conclusions Based on the data of the vibrational spectra of sulfonium C-dinitro ylides and the quantum-chemical calculation of the electronic structure of the molecule the nitro groups of dinitro ylides in their electronic structure differ substantially from the nitro groups of both the gem-dinitroalkanes and their salts.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 6, pp. 1407–1409, June, 1981.
