Abstract: By the method of electron transfer catalyzed reaction(ETC),the inert compound fluorotribromomethane can be activated by the electron donor 1,4-dilithioretraphenyl butadiene and the reaction will take place between them.The structure of the reaction product 1,4-difluorotetraphenyl benzene(Ⅰ) was determined by MS, NMR,and X-ray single crystal diffraction.Their comformations were calculated by molecular mechanics.
