Aromatic hydrocarbons complexed with a Cr(CO)3 unit react with benzaldehydes and furfural in THF and in 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.

Aromatic hydrocarbons complexed by a Cr(CO)3 unit react in THF and in the presence of t-BuOK, at the benzylic position with (COOEt)2 and PhCHO to give good yields of condensation products.With PhCHO formation of ketone via in situ Oppenauer-Woodward oxidation, is observed.

The complexation of a Cr(CO)3 unit to an aromatic hydrocarbon enhances the benzylic position towards attack by base and the resulting carbanion reacts with carbonyl compounds to produce a complexed alcohol; this reaction may be used to functionalize the benzylic position of an aromatic hydrocarbon.
