摘要

Single crystal X-ray structures of two bridgehead dienes are reported. The bridgehead double bonds of diene 7 show only modest deviation from strain-free tetrasubstituted double bonds. The double bonds in bridgehead diene 6, however, exhibit an average deviation of the C—C C—C torsion angle (φ+ χ) of 14°.
