THE ALLEGED ISOLABLE 1,4,5,6-TETRACHLORO-7,7-DIMETHOXYNORBORNADIENE-2,3-DICARBOXYLIC ANHYDRIDE
Addition of dibromomaleic anhydride to tetrachlorocyclopentadienone dimethyl acetal gives the pseudo-lactone 11 (X-ray crystal structure analysis) and not the mixture of endo- and exo-adducts 2 previously claimed; reduction of this product with Zn/HOAc gives 13 and 14 rather than the putative isolab...

Summary: | Addition of dibromomaleic anhydride to tetrachlorocyclopentadienone dimethyl acetal gives the pseudo-lactone 11 (X-ray crystal structure analysis) and not the mixture of endo- and exo-adducts 2 previously claimed; reduction of this product with Zn/HOAc gives 13 and 14 rather than the putative isolable norbornadienone acetal 3. |
