Benzocyclo-octenes. Part 5. Thermal Rearrangements of Benzocyclo-octenes to Benzocyclopropapentalenes.
Barton, John W.,Shepherd, Michael K.
, p. 961 - 966 (2007/10/02)
Substituted benzocyclo-octenes may undergo thermal rearrangement to 2a,2b,6b,6c-tetrahydrobenzocyclopropapentalenes.The ease of this reaction depends on the substituents, and is facilitated by the presence of phenyl groups in the 6- and 9- positio
