実験手順
The dipropargylmalonic acid (26 gm, 0.443 mol) was heated neat at 135 C until CO2 stopped evolving. It was then allowed to cool to an oil. The oil was distilled at 0.5 psi. The remaining oily residue in the distillation flask and solid were combined (15.7 gm, 79.9% yield) and was used as is in the next step.
