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 interaction between 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。
