PEPPSI-type 2-methyl-2-propenyl-functionalized N-heterocyclic carbene-palladium complexes: Synthesis, structural characterization and catalytic activity on Suzuki-Miyaura reaction
Sahin, Neslihan (ELSEVIER SCIENCE BV, 2019)N-Heterocyclic carbenes (NHCs) have been known to be efficient ligands for the Suzuki-Miyaura cross-coupling. In this work, four novel 2-methyl-2-propenyl substituted N-heterocyclic carbene ligands (1a-d) were synthesized ... -
Resorcinarene-Functionalised Imidazolium Salts as Ligand Precursors for Palladium-Catalysed SuzukiMiyaura Cross-Couplings
Sahin, Neslihan; Semeril, David; Brenner, Eric; Matt, Dominique; Ozdemir, Ismail; Kaya, Cemal; Toupet, Loic (WILEY-V C H VERLAG GMBH, 2013)Three imidazolium salts based on a rigid resorcinarene platform (13) were synthesised and used as catalyst precursors in the SuzukiMiyaura cross-coupling of aryl halides with phenylboronic acid. In these pro-carbene ligands, ... -
