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—CC—C torsion angle (φ + χ) of 14°.
报道了两个桥头二烯的单晶X射线结构。二烯7的桥头双键仅显示出与无应变的四取代双键的适度偏差。然而,桥头二烯6中的双键表现出CC-C-CC扭转角(φ+χ)的平均偏差为14°。
