“…88 The carbonyl-directed CH activation performed in the presence of MeOBIPHEP allowed the formation of the arylated derivative in 58% yield with 70% ee. The enantioselective intermolecular gold-catalyzed hydroarylation of diarylallenes was described employing indoles as nucleophiles (eq 64).…”

“…With Iridium In 2008, Tsuchikama et al [89] reported the use of the cationic Ir-bidentate phosphane complex formed from [Ir(COD) 2 ]BF 4 and BINAP (2,2 ′ -Bis(diphenylphosphino)-1,1 ′ -binaphthyl) for the catalytic addition of ortho-C-H bonds of aryl ketones to alkynes and alkenes, which gave alkenylated products in good to high yield (Scheme 4.14).…”

“…In the reaction of 1-naphthols, an [IrCl(cod)] 2 /PtBu 3 catalyst system is effective for the C-H bond alkenylation at the peri position (Scheme 18.86) [85]. Recently, Shibata and coworkers [86] reported that aromatic ketones undergo ortho alkenylation in the presence of a cationic Ir catalyst. Electron-rich arenes and heteroarenes are known to react with alkynes in the presence of Pd II or Pt II catalysts in acidic solvents to give the corresponding alkenylated products.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
