01,607,9]nona-2,4-dienes have also been prepared; the ready thermal electrocyclic rearrangement of the anti-isomeric tricyclo[4,3,01,607,9]nonadiene has been observed to give the bicyclo[6,1,0]nonatriene system. In addition the ready thermal cycloreversion reactions of the previously postulated polychlorotricyclo[6,2,1,02,7]undeca-3,5,9-triene and the heterocyclic 9,10-diaza-analogue have been kinetically
通过多氯二氮杂四环[6,2,1,1 3,6 0 2,7 ] dodeca- 4,9-二烯的热和光化学脱氮反应合成顺式和反式稠环双环[2,1,0]戊烷的潜力并探索了由常见起始原料制备的聚氯二氮杂三环[6,2,1,0 2,7 ] -undeca-3,5,9-三烯。迄今为止,已经制备了未知类型的内聚,顺-聚氯四环[5,2,1,0 2,6 0 3,5 ]癸烯,并对其动力学进行了异常快速的立体构型,转化为内聚-反异构体。迄今为止未知的烃类型的多氯实例还制备了顺-和反-三环[4,3,0 1,6 0 7,9 ]壬娜-2,4-二烯;已经观察到反异构体三环[4,3,0 1,6 0 7,9 ]壬二烯的现成的热电环重排得到双环[6,1,0]壬二烯系统。此外,还对动力学进行了先前假定的多氯三环[6,2,1,0 2,7 ] undeca-3,5,9-三烯与杂环9,10-二氮杂类似物的现成热环还原反应的研究,其反应速
