A Hemilabile and Cooperative N-Donor-Functionalized 1,2,3-Triazol-5-Ylidene Ligand for Alkyne Hydrothiolation Reactions
Strydom, Ian; Guisado-Barrios, Gregorio; Fernandez, Israel; Liles, David C.; Peris, Eduardo; Bezuidenhout, Daniela Wiley (2017)A series of novel cationic and neutral Rh complexes with an N-donor-functionalized 1,2,3-triazol-5-ylidene (TRZ) ligand (in which the pendant N donor is NHBoc, NH2, or NMe2) is described. The catalytic activity of these ... -
A rhodium(I)–oxygen adduct as a selective catalyst for one-pot sequential alkyne dimerization-hydrothiolation tandem reactions
kleinhans, George; Guisado-Barrios, Gregorio; Liles, David C.; Bertrand, Guy; Bezuidenhout, Daniela Royal Society of Chemistry (2016-01)An air-stable rhodium(I)–oxygen adduct featuring a CNC-pincer ligand, based on 1,2,3-triazol-5-ylidenes, catalyzes the homo-dimerization and hydrothiolation of alkynes, affording the gem-enyne and α-vinyl sulfide isomers, ... -
Diverse Coordination Modes of Bidentate COC and Tridentate CNC Ligands Comprising 1,2,3-Triazol-5-ylidenes
Tolley, Lewis C.; Strydom, Ian; Louw, Wynand J.; Fernandes, Manuel A.; Bezuidenhout, Daniela; Guisado-Barrios, Gregorio American Chemical Society (2019)Two readily available bis(1,2,3-triazol-5-ylidene) ligand precursors [H2(COC)](PF6)2 and [H2(CHNC)](PF6)2, bridged by an ether or amine functionality, respectively, were prepared. Their coordination versatility was evaluated ... -
Isolation of a potassium bis(1,2,3-triazol-5-ylidene) carbazolide: a stabilizing pincer ligand for reactive late transition metal complexes
Bezuidenhout, Daniela; Kleinhans, George; Guisado-Barrios, Gregorio; Liles, David C.; Üng, Gaël; Bertrand, Guy Royal Society of Chemistry (2014)The synthesis and X-ray crystal structure of a potassium adduct of a monoanionic CNC-pincer ligand featuring two mesoionic carbenes is reported. Owing to the peculiar electronic and steric properties of this ligand, the ... -
Nucleophilic T-Shaped (LXL)Au(I)-Pincer Complexes: Protonation and Alkylation
Kleinhans, George; Hansmann, Max M.; Guisado-Barrios, Gregorio; Liles, David C.; Bertrand, Guy; Bezuidenhout, Daniela American Chemical Society (2016-11)We report the synthesis and reactivity of unusual T-shaped (LXL)Au(I)-pincer complexes, based on a carbazole framework flanked by two mesoionic carbenes (MICs). In contrast to other Au(I) complexes, these complexes react ... -
Ruthenium(II) pincer complexes featuring an anionicCNC bis(1,2,3-triazol-5-ylidene)carbazolide ligand coordinatedin a meridional fashion
Kleinhans, George; Guisado-Barrios, Gregorio; Peris, Eduardo; Bezuidenhout, Daniela Elsevier (2018)The preparation of a new neutral ruthenium(II) pincer complexes with formula [RuCl(CO)2(CTRZNCTRZ)] (CNC = bis(1,2,3-triazol-5-ylidene)carbazolide) is described. Access to the hydrido complex [RuH (CO)2(CTRZNCTRZ)] was ...
