Aromatic hydrocarbons complexed with a Cr(CO)3 unit react with benzaldehydes and furfural in THF and in the presence of t-BuOK at the benzylic position to give condensation products in good yields. Formation of ketones by “in situ Oppenauer-Woodward” oxidation is observed. Influence of ring substituents on this formation is discussed.
