Abstract
The construction of α‐(hetero)aryl ethenesulfonyl fluorides was achieved via a Pd‐catalyzed Suzuki coupling of arylboronic acids with 1‐bromoethene‐1‐sulfonyl fluoride (1‐Br‐ESF). The novel α‐aryl ethenesulfonyl fluorides were found to be another selectively addressable bis‐electrophile for wide diversification through SuFEx click chemistry, or Michael addition with excellent chemical discrimination.
