An efficient catalyst-free radical cross-coupling reaction between aromatic aldehydes
and sulfoximines was developed. The reaction took place in the presence of N-bromosuccinimide as the radical initiator under microwave irradiation to afford the
corresponding acylated sulfoximines in moderate to excellent yields (27 examples).
This protocol proved to be rapid, easy to handle, and applicable to a broad scope
of substrates.
