Abstract:
A method for the regioselective carboxylation of (η6-alkylarene)tricarbonylchromium complexes at the benzylic position has been developed via the reaction of the corresponding lithium derivatives with carbon dioxide in tetrahydrofuran; a method for the preparation of 5-acetoxy-3-benzyl-1,4-methano-2,3-4,5-tetrahydro-1H-3-benzazepine from 1-tetralol is described.
