[reaction: see text] A series of cyclic mono- and dichloroenediynes have been prepared using an intramolecular carbenoid coupling reaction. The halogen atom had a retardative effect on Bergman cycloaromatization in every case examined, and atom transfer chemistry was demonstrated, resulting in formation of adducts.
