摘要

Abstract The 1 H NMR spectra of a number of new derivatives of benzobicyclo [3.1. 1] heptene were examined and interpreted by using a single set of coupling constants. All the compounds belonging to this system are in a γ-shaped configuration. Surprisingly, two different proton-proton spin-spin coupling constants (4 J= 5.5 to 6 Hz and 8.5 Hz) were obtained for the cyclobutane ring.
