Abstract

A palladium-catalyzed reductive carbonylation enables a facile and practical synthesis of aromatic aldehydes from aryl iodides and HCOOH. HCOOH serves not only as convenient and environmental-friendly C1 source but also as the reviving agent in the reductive elimination process of a Pd-catalyst.
