    • Routinely, the alkynyl-β-ketosulfones (1) were not purified from their precursors (6) (Scheme III) due to similar Chromatographic properties. The yields in Table I were calculated taking into account the fact that only component (1) is transformed by the aluminium amalgam.

    • It is noteworthy that all the allenes were stable to chromatography on silica gel and elution with a hydrocarbon solvent enabled facile removal of traces of unreacted starting material.
