Diiodobutadiyne (1,4-diiodobuta-1,3-diyne) is an organoiodine compound with the chemical formula C4I2. Its structure is I−C≡C−C≡C−I. It is a white solid. It is used in the creation of the polymer poly(diiododiacetylene) (PIDA) by undergoing 1,4 polymerization. It is a small linear molecule related to diacetylene, where the hydrogens of diacetylene is replaced by iodine.[1]
Diiodobutadiyne is light sensitive and explosive if stored out of solution as a dry solid. It will undergo random 1,2 and 1,4 polymerization, as well as decomposition in solution if kept over an extended period of time, having a half-life of just about two weeks.[2]
