Sažetak

Dicarbomethoxy-tetraehloronorbornadienone aeetal le rearranges
spontaneously to hemimelitate 3c while the corresponding anhydride 14 is stable up to 200oC. This result supports the hypothesis that the thermal rearrangement of substituted norbornadienes to aromatic products occurs by rate determining formation of norcaradiene intermediates.
