hydrocarbon which had been prepared previously by gas phase thermolysis of compound 6. The first method is based on an unusual dipolar cycloaddition of dichloroketene onto bullvalene. After reductive dechlorination, a Shapiro-Heath reaction of the tosylhydrazone gave the title compound. Alternatively, compound 13 is also obtained fromits isomer 6 by a Ag+ catalyzed reaction.
在此,我们描述了一种重要的C 12 H 12烃的两种独立且非热解的合成,该烃是先前通过化合物6的气相热解制备的。第一种方法是基于二氯乙烯酮在buvalene上的不寻常的偶极环加成。还原脱氯后,甲苯磺酰腙的夏皮罗-希思反应得到标题化合物。或者,化合物13也可以通过Ag +催化反应从其异构体6获得。
