This cyclometalated ruthenium complex absorbs in the visible-light region and can undergo a photochemical C−H functionalization reaction, as shown in control ...

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

WebApr 2, 2024 · Investigations of the underlying electronic structure and bonding scheme by resorting to quantum chemical methods of the density functional theory have revealed the key role played by the electron-donating NMe 2 substituent, which enables the a priori antagonistic π-coordination of the in situ-formed cationic ruthenacycle by a dicationic (η … WebDec 3, 2024 · Three ruthenacycle complexes 5q, 5v, and 5wwere thereby isolated and complex 5wwas unambiguously characterized by X-ray diffraction analysis (Scheme 4a). It is noteworthy that the 1H NMR resonances of the ruthenacycle complexes in [D 4]-MeOH were split into two sets of resonances in contrast to the 1H NMR in CDCl 3, which showed only … WebA diyne diester afforded a dinuclear ruthenacycle complex similar to known iron ferrole complexes and a mononuclear ruthenacyclopentadiene complex. The selectivity for the formation of these products varied depending on the ratio of the diyne diester toward [Ru 3 (CO) 12]. When a phenyl-substituted diyne was employed, a cyclopentadienone ... drvcw560
