The curtius rearrangement of isomeric cycloheptatrienecarboxylic and norcaradienecarboxylic acids
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19571. The Curtius rearrangement in isomeric β- and γ-cycloheptatrienecarboxylic acids and norcaradlenecarboxylic acid was studied. It was shown that rearrangement goes without isomerization of the migrating hydrocarbon radical under the conditions employed. 2.
