Abstract
1. When the cyclohexane ring is trans-condensed with a five-membered anhydride ring and a bicyclic system the C-C bonds of the bicyclic system occupy equatorial positions. 2. The stereochemistry of the diene synthesis of hexachlorocyclopentadiene with the anhydrides of cis- and trans-3-methyl-4-cyclohexene-1,2-dicarboxylic acids is determined by the configuration of the methyl group. 3. The addition of maleic anhydride to the diene system of the anhydride of 1,2,3,4-tetracehlorobicyclo[4.4.0]decadiene-8,9-dicarboxylic acid goes in the trans-position to the bonds of the cyclohexane ring.
