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 Photoinduced Heterogeneous C-H Arylation by a Reusable Hybrid Copper Catalyst, published in 2020, which mentions a compound: 92-71-7, Name is 2,5-Diphenyloxazole, Molecular C15H11NO, HPLC of Formula: 92-71-7.
Heterogeneous copper catalysis enabled photoinduced C-H arylations of heteroarenes with aryl halides under exceedingly mild conditions at room temperature to afford aryl heteroarenes such as I [R = H, 6-OMe, 5-Cl, etc.; Ar = Ph, 4-MeC6H4, 2-MeOC6H4, etc.; X = O, S, NMe]. The hybrid copper catalyst could be reused without significant loss of catalytic efficacy. Detailed studies in terms of TEM, HRTEM and XPS anal. of the hybrid copper catalyst, among others, supported its outstanding stability and reusability.
Compounds in my other articles are similar to this one(2,5-Diphenyloxazole)HPLC of Formula: 92-71-7, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
