Interestingly, the corresponding (E)-haloalkenes are obtained under anhydrous conditions. Simple 1,1,2-triiodo compounds can be prepared by treatment of the corresponding vinylstannane with iodine in carbon tetrachloride (Equation (115)) <2001JACS1768>. O OH O HO H NIS, cat. 4 21 Diiodoalkanes from Alkynes As is well documented in the literature, 2 equiv. of hydrogen iodide adds to terminal alkynes to produce diiodoalkanes (see Hill (COFGT 1995)). In this case, diiodination occurs at the internal alkynyl carbon (Equation (116)).
