[1071-98-3] C4N2 (MW 76.06) InChI = 1S/C4N2/c5-3-1-2-4-6 InChIKey = ZEHZNAXXOOYTJM-UHFFFAOYSA-N (nucleophilic addition;4, 5 [4 + 2] cycloaddition reactions;2 metal complexes insertion reactions3) Physical Data: bp 76.5 °C; mp 20.5 °C; d 0.9703 g cm−3; IR 2268 cm−1 (w), 2212 cm−1 (m). Solubility: sol all organic liquids. Form Supplied in: clear colorless liquid. Preparative Methods: see eq 1. (1) Purification: by simple vacuum sublimation or atmospheric distillation. Handling, Storage, and Precautions: the solid compound can be stored indefinitely at dry-ice temperatures and is handled at rt. It is much more sensitive to the presence of oxygen, a polymerization or condensation reaction probably taking place.
