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 direct C2-arylation of azoles with aromatic triazenes, published in 2019, which mentions a compound: 118994-89-1, Name is Ethyl oxazole-5-carboxylate, Molecular C6H7NO3, Application of 118994-89-1.
A highly efficient palladium-catalyzed arylation of azoles at the C2-position using 1-aryltriazenes as aryl reagents was developed for the synthesis of aryl azoles, e.g., I. Azoles including oxazoles, thiazoles, imidazoles, 1,3,4-oxadiazoles and oxazolines reacted with 1-aryltriazenes smoothly to generate the corresponding products in good to excellent yields and various substitution patterns were tolerated toward the reaction.
After consulting a lot of data, we found that this compound(118994-89-1)Application of 118994-89-1 can be used in many types of reactions. And in most cases, this compound has more advantages.
