Additive-free, <i>N</i> -chlorosuccinimide-promoted electrophilic phosphorothiolation/cyclization of alkynes with P(O)SH compounds to access heterocyclic phosphorothiolated molecules

Abstract

A N -chlorosuccinimide-promoted electrophilic phosphorothiolation/cyclization of alkynes for the construction of phosphorothiolated heterocycles under metal- and additive-free conditions has been developed.
