Simon, Marc-Olivier published the artcileRuthenium-catalyzed C-H bond activation of Michael acceptors: an unusual reactivity leading to allylsilanes, Name: (R)-5,5′-Bis(diphenylphosphino)-2,2,2′,2′-tetrafluoro-4,4′-bi-1,3-benzodioxole, the publication is Advanced Synthesis & Catalysis (2009), 351(1+2), 153-157, database is CAplus.
The authors report here an improved catalyst for the functionalization of Michael acceptors, involving C-C bond formation via C-H bond activation, using an in situ generated Ru active species. On some particular substrates, the C-H functionalization resulted unexpectedly in the formation of allylsilanes rather than in the expected conjugated adducts, affording a new straightforward methodol. to access useful stereodefined trisubstituted allylsilanes via C-H bond activation. Preliminary results showed that they were reactive in the allylation of aldehydes, providing an access to alcs. bearing a quaternary C center.
