Abstract
Abstract It has been shown that the reactions of tricarbonyl (η 6-2-lithiothiophene) chromium (O) with various arene carboxaldehydes yields mixtures of unequal amounts of diastereoisomers, which can be separated by flash chromatography. The structures of the products have been established by 1 H NMR spectroscopy and by independent synthesis. A novel synthesis of tricarbonyl (η 6-thiophene)-chromium (O)(1) is described.
