From: Accessing gold p-acid reactivity under electrochemical anode oxidation (EAO) through oxidation relay

A Initial attempts for π-acid activation under EAO conditions. B By-passing [L-AuI-Ar] to prevent side reactions. C Hydrazine serves as aryl electrophile “sarrogate” for the initiation of oxidation relay.
