Zhou, Hua published the artcileThe research to the condition of catalytic degradation of borofluoric acid diazonium salt, Application of Bis(4-fluorophenyl)methane, the publication is Shandong Huagong (2009), 38(1), 18-20, database is CAplus.
The influencing factors of the the catalytic degradation of borofluoric acid diazonium salt were discussed, which was the key step to synthesize 4,4′- difluorobenzophenone. It was found that with iron powder as catalyst and adding dry diazonium salt to toluene whose volume was triple-weight of diazonium salt, the reaction could be occurred smoothly; and with those conditions the yield of the reaction could be up to 85% and the purity could be 94% (with GC detection).
Shandong Huagong published new progress about 457-68-1. 457-68-1 belongs to catalysis-chemistry, auxiliary class Fluoride,Benzene, name is Bis(4-fluorophenyl)methane, and the molecular formula is C23H20BN, Application of Bis(4-fluorophenyl)methane.
