Atom transfer radical addition (ATRA) of 2-chlorodithiane onto aryl alkynes through the use of di-tert-butyl peroxide as an oxidant at room temperature directly affords a variety of synthetically valuable beta-chloro-(Z)-vinyl dithianes in good yields with high regioselectivities and without the assistance of any transition metals. It provides an operationally simple pathway to access vinyl dithianes with controlled formation of a new C(sp(2))-C bond and a C(sp(2))-Cl bond.
