Prakash, G. K. Surya; Mathew, Thomas; Hoole, Dushyanthi; Esteves, Pierre M.; Wang, Qi; Rasul, Golam; Olah, George A. published the artcile< N-Halosuccinimide/BF3-H2O, Efficient Electrophilic Halogenating Systems for Aromatics>, SDS of cas: 2265-92-1, the main research area is halosuccinimide trifluoroborane monohydrate electrophile halogenation aromatic.
N-Halosuccinimides (NXS, 1) are efficiently activated in trifluoromethanesulfonic acid and BF3-H2O, allowing the halogenations of deactivated aromatics Because BF3-H2O is more economic, easy to prepare, nonoxidizing, and offers sufficiently high acidity (-H0 ≈ 12, only slightly lower than that of trifluoromethanesulfonic acid), an efficient new electrophilic reagent combination of NXS/BF3-H2O has been developed. DFT calculations at the B3LYP/6-311++G**//B3LYP/6-31G* level suggest that protonated N-halosuccinimides undergo further protosolvation at higher acidities to reactive superelectrophilic species capable either in the transfer of X+ from the protonated forms of NXS to the aromatic substrate or in forming a highly reactive and solvated X+ which would readily react with the aromatic substrates. Structural aspects of the BF3-H2O complex have also been investigated.
Journal of the American Chemical Society published new progress about Acid catalysis. 2265-92-1 belongs to class iodides-buliding-blocks, and the molecular formula is C6H3F2I, SDS of cas: 2265-92-1.
