Sulfur-Boron Lewis Pair-Catalyzed Hydrohalogenation of Alkynes via Formal Hydrogen Atom Transfer.

The catalytic synthesis of both (E)- and (Z)-haloalkenes from internal aryl alkyl alkynes via a sulfur-boron Lewis pair has been developed. The catalytically active Lewis pair complex is generated in situ from 2-naphthalenethiol and B(C6F5)3, enabling the selective synthesis of chloro-, bromo-, and iodoalkenes with exc...
