Computed Properties of C12H8Br2. I found the field of Chemistry very interesting. Saw the article Triptycenyl Sulfide: A Practical and Active Catalyst for Electrophilic Aromatic Halogenation Using N-Halosuccinimides published in 2020, Reprint Addresses Nishii, Y (corresponding author), Osaka Univ, Grad Sch Engn, Frontier Res Base Global Young Researchers, Suita, Osaka 5650871, Japan.; Miura, M (corresponding author), Osaka Univ, Grad Sch Engn, Dept Appl Chem, Suita, Osaka 5650871, Japan.. The CAS is 92-86-4. Through research, I have a further understanding and discovery of 4,4′-Dibromobiphenyl.
A Lewis base catalyst Trip-SMe (Trip = triptycenyl) for electrophilic aromatic halogenation using N-halosuccinimides (NXS) is introduced. In the presence of an appropriate activator (as a noncoordinating-anion source), a series of unactivated aromatic compounds were halogenated at ambient temperature using NXS. This catalytic system was applicable to transformations that are currently unachievable except for the use of Br-2 or Cl-2: e.g., multihalogenation of naphthalene, regioselective bromination of BINOL, etc. Controlled experiments revealed that the triptycenyl substituent exerts a crucial role for the catalytic activity, and kinetic experiments implied the occurrence of a sulfonium salt [Trip-S(Me)Br][SbF6] as an active species. Compared to simple dialkyl sulfides, Trip-SMe exhibited a significant charge-separated ion pair character within the halonium complex whose structural information was obtained by the single-crystal X-ray analysis. A preliminary computational study disclosed that the pi system of the triptycenyl functionality is a key motif to consolidate the enhancement of electrophilicity.
