Notes:
A range of 3-(para-substituted-phenyl)-3-halodiazirines have been prepared and their 13C and 19F NMR spectra measured. Calculated with these data were the susceptibility coefficients ρI and ρR of the inductive (σI) and resonance (σR0) effects, respectively, to substituent-induced chemical shift differences at the diazirine carbon (13C NMR) and the 3-fluorine (19F NMR of the 3-fluorodiazirine series). An inverse relationship was found between the susceptibility parameters and the electronegativity of the halo substituent at the diazirine carbon.
