The Reaction of Carbon Monoxide with Organometallic Compounds.

Abstract

Abstract The reaction of iron pentacarbonyl with aryllithiums at −50∼60°C has yielded the corresponding aromatic aldehydes in good yields. 2,6-Dimethylbenzaldehyde (36.4%), 2,4-dimethylbenzaldehyde (65.4%), p-t-butylbenzaldehyde (47.0%), o-t-butylbenzaldehyde (54.3%), p-methoxybenzaldehyde (24.2%) and 2,4,6-trimethylbenzaldehyde (60.5%) have been prepared by this method.
