1,2-Diiodoethane is an organoiodine compound.
It is most commonly used in organic synthesis in the preparation of Samarium (II) Iodide or Ytterbium (II) Iodide in THF.
In mass spectroscopy, 1,2-diiodoethane exhibits 5 major peaks, with the base peak showing at 155 m/z, which is the loss of one iodide molecule of 126 g/mol.
1,2-Diiodoethane can be synthesized by bubbling ethene into pure liquid iodine at room temperature.
By formula: C2H4 + I2 = C2H4I2
