The Reaction of Norbornene with Lead Tetraacetate and Thallium Trinitrate. Preliminary communication

Helvetica Chimica Acta, 1972
AbstractThe reaction of norbornene with lead tetraacetate is found to be much more complex than previously reported. In acetic acid and in benzene, the syn‐7‐norbornenyl, 3‐nortricyclyl, and syn and anti‐7‐acetoxy‐exo‐2‐norbornyl acetates were characterized.
