In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Palladium-Catalyzed Annulation of o-Iodobiphenyls with o-Bromobenzyl Alcohols: Synthesis of Functionalized Triphenylenes via C-C and C-H Bond Cleavages, published in 2013-10-18, which mentions a compound: 175136-62-6, Name is Tris(3,5-bis(trifluoromethyl)phenyl)phosphine, Molecular C24H9F18P, Reference of Tris(3,5-bis(trifluoromethyl)phenyl)phosphine.
Treatment of o-iodobiphenyls with o-bromobenzyl alcs. in the presence of cesium carbonate under palladium catalysis affords a series of highly substituted triphenylenes [e.g., o-iodobiphenyl + 2-(2-bromophenyl)-2-propanol in presence of PdCl2(NCPh)2/P[3,5-(CF3)2C6H3]3 and Cs2CO3 afforded triphenylene in 81% yield].. The reaction involves two C-C bond formations and C-C and C-H bond cleavages. A combination of palladium and an electron-deficient phosphine ligand proves to be effective for both decarbonylative cross-coupling and intramol. cyclization.
There is still a lot of research devoted to this compound(SMILES：FC(C1=CC(C(F)(F)F)=CC(P(C2=CC(C(F)(F)F)=CC(C(F)(F)F)=C2)C3=CC(C(F)(F)F)=CC(C(F)(F)F)=C3)=C1)(F)F)Reference of Tris(3,5-bis(trifluoromethyl)phenyl)phosphine, and with the development of science, more effects of this compound(175136-62-6) can be discovered.
