    • Experimental Details 1H NMR and 13C NMR spectra were obtained on a BRUKER Avance 400. Proton spectra were referenced to TMS; 13C NMR spectra refer to the solvent signal at δ, 77.0 ppm. Spectra in DMSO-d6 were referenced to δ, 2.50 ppm (1H) and 39.7 ppm (13C, respectively. High-resolution mass spectra were measured with a Bruker Daltonik APEX IV FT Ion Cyclotron Resonance mass spectrometer with electrospray ionization. 1-(2-Chloro-5- pyridylmethyl)-2-(2,3,3-trichloro-1-nitroallylidene)imidazolidine (3) To a solution of 7.19 g (38.7 mmol) N-(2-chloro-5-pyridylmethyl)ethane-1,2- diamine in 30 mL MeOH was added a solution of 5.00 g (18.4 mmol) 1,1,2,4,4-pentachloro-3-nitro-1,3-butadiene (1) in 5 mL MeOH at -40°C within 5 min. The resulting mixture was kept at -40°C for 1 h, then 1 h at r.t. The precipitate was sucked off, washed with H2O (3 x 20 mL, MeOH 1 x 10
