This work describes the selective desoxygenation of epoxides to olefins using carbon monoxide as the reducing agent and an iridium pincer complex as the homogeneous catalyst. A lithium salt additive acts as co-catalyst in various steps of the catalytic cycle. The mechanism is elucidated including the isolation of intermediates.
