from the readily available α,β‐unsaturated ketone, 3‐tert‐butyl‐4,4‐dimethyl‐2‐pentenal, higher vinylogues, and fully terminally tert‐butylated polyolefins with up to 13 consecutive conjugated double bonds have been prepared by either McMurry dimerization or Wittig chain‐elongation routes. The highly unsaturated conjugated π systems, which show a remarkable stability, have been characterized by spectroscopic
从容易获得的α,β-不饱和酮,3-叔丁基-4,4-二甲基-2-戊烯,高级乙烯基化合物和具有多达13个连续共轭双键的全叔叔丁基化聚烯烃制备如下: McMurry二聚化或Wittig链延长路线。表现出显着稳定性的高度不饱和共轭π系统已通过光谱方法进行了表征,并且在许多情况下已通过X射线结构分析进行了表征。产率高到足以进行彻底的化学反应性研究。
