New route to synthesis of PVP-stabilized palladium(0) nanoclusters and their enhanced catalytic activity in Heck and Suzuki cross-coupling reactions
Durap, Feyyaz; Metin, Önder; Aydemir, Murat; Özkar, Saim (Wiley, 2009)Herein we report a new method for the synthesis and characterization of PVP-stabilized palladium(0) nanoclusters and their enhanced catalytic activity in Suzuki coupling and Heck reactions of aryl bromides with phenylboronic ... -
Ruthenium(0) nanoclusters supported on hydroxyapatite: Highly active, reusable and green catalyst in the hydrogenation of aromatics under mild conditions with an unprecedented catalytic lifetime
Zahmakıran, Mehmet; Tonbul, Yalçın; Özkar, Saim (Royal Society of Chemistry, 2010)The preparation of ruthenium(0) nanoclusters supported on hydroxyapatite and their characterization by a combination of complementary techniques are described. The resultant ruthenium(0) nanoclusters provide high activity ... -
Synthesis and characterization of new (N-diphenylphosphino)-isopropylanilines and their complexes: crystal structure of (Ph2P=S)NH-C6H4-4-CH(CH3)2 and catalytic activity of palladium(II) complexes in the Heck and Suzuki cross-coupling reactions
Aydemir, Murat; Baysal, Akın; Gürbüz, Nevin; Özdemir, İsmail; Gümgüm, Bahattin; Özkar, Saim; Çaylak, Nagihan (Wiley, 2010)Three new (N-diphenylphosphino)-isopropylanilines, having isopropyl substituent at the carbon 2- (1) 4- (2) or 2,6- (3) were prepared from the aminolysis of chlorodiphenylphosphine with 2-isopropylaniline,4-isopropylaniline ... -
Synthesis and characterization of transition metal complexes of thiophene-2-methylamine: X-ray crystal structure of palladium (II) and platinum (II) complexes and use of palladium(II) complexes as pre-catalyst in Heck and Suzuki cross-coupling reactions
