We show in this work that certain soluble metal compounds based on iron are active catalysts for the asymmetric transfer hydrogenation of aromatic ketones. This is significant because iron-based catalysts are potentially of lower cost, toxicity and environmental impact than those of platinum metals. Asymmetric hydrogenation allows the economical production of just the right- or left-handed alcohol desired as a fragrance or pharmaceutical intermediate.
