SDS of cas: 118994-89-1. 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: Ethyl oxazole-5-carboxylate, is researched, Molecular C6H7NO3, CAS is 118994-89-1, about Direct C2-Heteroarylation of Indoles by Rhodium-Catalyzed C-C Bond Cleavage of Secondary Alcohols. Author is Yu, Tian-Yang; Zheng, Zhao-Jing; Sun, Wei; Qiao, Zi-Heng.
A rhodium-catalyzed direct heteroarylation of indoles by cleavage of an inert C-C bond of alcs. is reported. This catalytic system exhibits high reactivity and tolerates various functional groups. This reaction provides a tool for the rapid construction of biheteroaryls without pre-activation of the starting materials. Control experiments were conducted to determine a possible mechanism. This reaction makes a significant contribution to the field of C-C bond activation of alcs.
