Abstract
X-Ray and NMR data are presented which suggest that
trans-cyclooctene, 9,9-dibromo-
trans-bicyclo[6.1.0]nonane,
trans-bicyclo[6.1.0]nonane and
trans-cyclooctene oxide exist in a distorted crown conformation. The synthesis of optically active
trans-bicyclo[6.1.0]nonane and
trans-cyclooctene oxide is described.
