Summary The displacement of the double bonds in diolefins has been investigated. The diolefins dirnethallyl and diallyl were first studied to determine various sets of conditions which would promote isomerization, and to establish a standard procedure for use with other hydrocarbons. After this a series of 1, 5-diolefins was subjected to catalytic alumina treatment, and the products were separated, studied and identified. The characteristics of ...
