Di-tert-butyl peroxide-mediated atom-transfer radical addition of 2-chlorodithiane to aryl alkynes under mild conditions.


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 β-chloro-(Z)-vinyl dithianes in good yields with high regioselectivities and without the assistance of any transition metals. It provides an operationally… (More)
