It was established by means of multinuclear magnetic resonance method (H-1, C-13, F-19 and N-14) that reaction of 2,2,6,6-tetramethyl-4-R-piperidin-1-oxyl radicals (R = H, OH, OMe, OCOPh, NHCOMe) with nitrosonium tetrafluoroborate gave rise to the corresponding 2,2,6,6-tetramethyl-1-oxo-4-R-piperidinium tetrafluoroborates. Linear correlations were found between the chemical shifts of atoms H-4, C-4 of cations and respectively sigma(1)-constants of substituents R and chemical shifts of C-4 atom calculated from increments of substitution. The conformational features of the generated nitrosonium cations are considered on the grounds of vicinal coupling constants J(HH) and quantum-chemical calculations by AM1 method.
