Synthesis
Dienochlor can be obtained by catalytic reduction of hexachlorocyclopentadiene (e.g. with copper or hydrogen).[2]
Properties
Dienochlor is a combustible yellow solid which is practically insoluble in water. It decomposes when heated above 250 °C. It decomposes rapidly under the influence of sunlight.
Applications
Dienochlor is used as an acaricide under the trade name Pentac for combating mites (Tetranychus, Polyphagotarsonemus latus) on roses, chrysanthemums, and other ornamental plants.[3]
