ABSTRACT:
Alkyl cyclohexa-1,3-dienes are aromatized with sulfur dioxide and oxygen. Cyclohexa-1,4-dienes are aromatized with sulfur dioxide. Conjugated dienic hydrocarbons, including alkyl cyclohexa-1,3-dienes, are converted to beta-olefinic peroxides by sulfur dioxide and oxygen. The aromatization reactions are useful as part of the synthesis of selected aromatics from acyclic olefins. The beta-olefinic peroxides are useful intermediates in the production of 1,4-diols.
