We did not find any suitable trifluoromethyl aryl diaziridines in the Cambridge Database for comparison, ‡ and so perused our own laboratory's library of diaziridine molecules from previous projects. We were successful in obtaining X-ray quality crystals of 3,5-bis(3-(trifluoromethyl)diaziridin-3-yl)pyridine, a molecule that was first synthesized by our group in 2019. The solved structure (CCDC 2369820) is shown in Fig. . As anticipated based on our earlier calculations, this control molecule (for which conjugation would not be expected, due to the saturated N-N bonds) adopted a staggered conformation, and had CF3-C-aryl bond angles of approximately 115°-consistent with a cyclopropane-like sp -hybridization state at the central carbon atom.
