title: Novel cyclization reaction of 1,omega-diiodo-1-alkynes without the loss of iodine atoms.
abstract: In the presence of 1-hexynyllithium (0.2-0.6 equiv.), 1,omega-diiodo-1-alkynes undergo a new type of cyclization reaction without the loss of two iodine atoms to afford (diiodomethylene)cycloalkanes.
