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 Tris-NHC-propagated self-supported polymer-based Pd catalysts for heterogeneous C-H functionalization, published in 2021, which mentions a compound: 87488-84-4, Name is 1-(2-Bromophenyl)-1H-pyrazole, Molecular C9H7BrN2, HPLC of Formula: 87488-84-4.
Three-dimensionally propagated imidazolium-containing mesoporous coordination polymer and organic polymer-based platforms were successfully exploited to develop single-site heterogenized Pd-NHC catalysts for oxidative arene/heteroarene C-H functionalization reactions. The catalysts were efficient in directed arene halogenation, and nondirected arene and heteroarene arylation reactions. High catalytic activity, excellent heterogeneity and recyclability were offered by these systems making them promising candidates in the area of heterogeneous C-H functionalization, where efficient catalysts are still scarce.
Compound(87488-84-4)HPLC of Formula: 87488-84-4 received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(1-(2-Bromophenyl)-1H-pyrazole), if you are interested, you can check out my other related articles.
