Abstract:
1,2-Di-tert-butyldiaziridine 1 has been synthesized for the first time and its 1H and 13C NMR spectra studied in comparison with model diaziridines 8–10. Its photoelectron and mass spectra have been measured and its structure optimized by semiempirical and ab initio calculations; considerable steric deformation of the CH2 ring fragment and mutual approach of tert-butyl groups is shown.
