Diene condensation of allylacetylene and allylethynyldimethylcarbinol with cyclopentadiene and some transformations of the obtained adducts

The diene condensation of allylacetylene and allylethynyldimethylcarbinol with cyclopentadiene proceeds, as in the case of hexachlorocyclopentadiene, with involvement of the vinyl group, but under more drastic conditions and with the formation of both the mono- and the bisadducts.
