7-(Phenylsulfonyl)-bicyclo[4.2.0]octa-1,3,5-triene as a synthetic intermediate.

Barbara D. Gowland
The role of 7-(phenylsulfonyl)-bicyclo[4.2.0]octa-1,3,5-triene (benzocyclobutene phenylsulfone (83)) as a synthetic intermediate is investigated. Attempts were made to prepare this compound by several new routes. Cyclization of 1-(chloromethyl),2-(phenylsulfonylmethyl)-benzene ( 127) was attempted with LDA, MeLi, and phase transfer conditions, as well as flash vacuum thermolysis. None of these modifications were successful. The synthesis of phenyl 2-(o-chlorophenyl)ethyl sulfone (80) was approached by a new route in moderate yields by condensation of the anion of methyl phenyl sulfone...
