The reaction of the bridged compounds camphene 1, norbornene 10, benzonorbornene 15, and dibenzobarrelene 22 with Pb(OAc)4-n.(N3)n confirms the suggestion of a polar reaction mechanism. The reactions point to carbonium intermediates, yielding 7, 14, 20, 21, 26, and 27 by characteristic skeletal rearrangement. The close resemblance of these reactions to the halogenation of the same bridged olefins under

one C6F4 moiety in either reactant, afford the janusenes 2 and 3, in which phenyl and tetrafluorophenyl rings are disposed in a close facial relationship. Compound 3, which is formed in a regiospecific manner, exhibits an ultraviolet spectrum that suggests a donor-acceptor interactionbetween the proximate -C6H4- and -C6F4- rings.
蒽与二苯并戊环烯的环加成反应,在任何一种反应物中均具有至少一个C 6 F 4部分,得到janusenes 2和3,其中苯基和四氟苯基环以紧密的面部关系设置。以区域特异性方式形成的化合物3表现出紫外光谱,表明在附近的-C 6 H 4-和-C 6 F 4-环之间存在供体-受体相互作用。
