Hydrogen-Bonding-Assisted Brønsted Acid and Gold Catalysis: Access to Both (<i>E</i>)- and (<i>Z</i>)-1,2-Haloalkenes via Hydrochlorination of Haloalkynes

Abstract

)-chlorohaloalkenes via hydrochlorination of haloalkynes, based on two distinct hydrogen-bond-network-assisted catalytic systems: Brønsted acid catalysis and gold catalysis. Both systems offer high stereoselectivity, good chemical yields, and diverse functional group tolerance.
