COA of Formula: C15H11NO. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 2,5-Diphenyloxazole, is researched, Molecular C15H11NO, CAS is 92-71-7, about Palladium/copper-catalyzed decarbonylative heteroarylation of amides via C-N bond activation.

A novel strategy for the synthesis of 2-arylated oxazole derivatives, e.g., 5-(1-naphthalenyl)-2-phenyloxazole via palladium/copper-catalyzed decarbonylative heteroarylation of amides RC(O)NR1R2 (R = C6H5, 2-FC6H4, 1-naphthyl, etc.; R1R2 = -C(O)(CH2)3C(O)-, -C(O)(CH2)2C(O)-) via C-N bond activation by ground-state destabilization has been reported. This transformation shows good functional group tolerance and delivers the versatile 2-arylated oxazole derivatives in moderate to good yields. This transformation provides unique and efficient strategies for converting readily available amides and the precursor carboxylic acids into valuable chems.
