    Abstract: A novel conjugated diene bisfunctionalization process wherein a nitro group and a hydroxyl group in the form of an ester are introduced into the conjugated diene molecule by treatment of conjugated dienes with nitric acid in the presence of an acid anhydride. The novel compounds produced by this process and transformation products thereof, are useful as bactericides and fungicides and valuable organic synthesis intermediates, A novel procedure for the production of nitriles and .gamma.-acetoxytiglic aldehyde is disclosed.
