Addition of hexamethylphosphoric triamide to solutions of prop-2-ynyl dilithio-derivatives causes the disappearance of their strong i.r. absorption bands at 1800-1900 cm-1 and the appearance of a medium new band at ca. 2050 cm-1, indicating that a structure trans-formation from an allenic to a sesquiacetylenic form has taken place.
