An indication that the interesting diallenic cyclic hydrocarbon 3 is indeed an intermediate in the transformation of 2 to 4 was obtained from hydrogenation experiments. Platinum oxide in ethanol and aqueous sodium hydroxide was reduced by stirring in hydrogen, a solution of 1 in ethanol was added, and the hydrogenation was continued until uptake ceased. Analysis by glpc showed that one of the components of the resulting complex mixture was ...
