Effect of immobilization on catalytic characteristics of saturated Pd-N-heterocyclic carbenes in Mizoroki-Heck reactions
Aksin, Ozge; Turkmen, Hayati; Artok, Levent; Cetinkaya, Bekir; Ni, Chaoying; Büyükgüngör, Orhan; Ozkal, Erhan (Elsevier Science Sa, 2006)A saturated Pd-N-heterocyclic complex was immobilized on an amorphous silica. The complex itself is of very high thermal stability. However, TEM observations, hot filtration, reusability, and poisoning tests all revealed ... -
[mu-1,1 '-Bis(2,4,6-trimethylbenzyl)-3,3 '-(2,3,5,6-tetramethyl-p-phenylenedibenzimidazole)-2,2 '-diylidene]di-mu-bromo-disilver(I)
Kosar, Basak; Turkmen, Hayati; Cetinkaya, Bekir; Büyükgüngör, Orhan (Blackwell Publishing, 2007)The title compound, [Ag2Br2(C46H50N4)], contains a bulky bis(N-heterocyclic carbene) ligand, comprising two benzimidazolium groups linked through a 2,3,5,6-tetramethyl-1,4-xylylene bridge. The compound was formed by reaction ... -
Piano-stool benzothiazol-2-ylidene Ru(II) complexes for effective transfer hydrogenation of carbonyls
Oruc, Zeynep Ipek; Gok, Lutfiye; Turkmen, Hayati; Sahin, Onur; Büyükgüngör, Orhan; Cetinkaya, Bekir (Elsevier Science Sa, 2016)Benzothiazolium bromides (NSHC center dot HBr) (1a-j) with a variety of alkyl chain or benzyl substituents on N atom were prepared. The synthesis of ruthenium(II) (NSHC) complexes, (2a-j) could be achieved by in situ ... -
Silver, palladium and rhodium complexes of acenaphthylene-anuilated N-heterocyclic carbene ligands: A comparative study
Turkmen, Hayati; Sahin, Onur; Büyükgüngör, Orhan; Cetinkaya, Bekir (Wiley-V C H Verlag Gmbh, 2006)The newly prepared carbene precursor 1,3-dimesitylacenaphtho[1,2-d]imidazolinium chloride, (NHC-H)Cl, 3, could be readily converted into the NHC-silver(l) complex, 4, which is an efficient carbene transfer agent and has ... -
Synthesis and structural characterization of Palladium(II) complex bearing N-Heterocyclic Carbene
Gokce, Aytac Gurhan; Turkmen, Hayati; Aygun, Muhittin; Cetinkaya, Bekir; Buyuekgungor, Orhan (Springer/Plenum Publishers, 2008)Trcitts-Bis[1,3-bis(2,4-dimethylphenylimidazolidin-2-ylidene)]dichloropalladium(II), 4, was prepared from 1,3-bis(2,4-dimetilphenyl)imidazoliniumchloride. The crystal and molecular structure of 4 have been determined by ...
