Abstract
There are disclosed herein derivatives of bisfunctionalized compounds, wherein said compounds have been formed by the introduction of a nitro group and a hydroxyl group in the form of an ester into a conjugated diene molecule by treatment of said conjugated dienes with nitric acid in the presence of a carboxylic acid anhydride. The novel compounds produced by this process are useful as bactericides, fungicides and valuable organic synthesis intermediates.
