摘要

Benzoylation of benzocyclobutene gives β-phenethyl chloride, 2′-(2-chloroethyl)- benzophenone and 4-benzoylbenzocyclobutene in proportions dependent on solvent and catalyst; β-phenethyl chloride gives no discrete benzoylation product under conditions where benzocyclobutene gives large quantities of the chloroethylbenzophenone. Sulphonation, using dioxan-sulphur trioxide complex, gives β-hydroxyethyl-benzene-o- ...
