WebFurther investigations on halide effects were performed notably by using a cationic ruthenacycle which was found to be an intermediate for the reaction. In order to rationalize the role played by the phosphinous acid, a mechanism involving a concerted metallation deprotonation favored by a phosphinito species has been proposed. WebFeb 24, 2024 · In recent years, straightforward C−H glycosylation 11 provided a reliable tools for the efficient and modular assembly of C-glycosides, 12 such as palladium-catalyzed ortho-C−H glycosylation. 13 In this context, our group found that the ruthenacycle A derived from ortho-C−H metalation allowed the glycosyl anomeric radical C addition at ... drv corona kurzantrag https://shift-ltd.com
