1H-1,2,3-Triazol-5-ylidenes: Readily Available Mesoionic Carbenes
Guisado-Barrios, Gregorio; Soleilhavoup, Michele; Bertrand, Guy American Chemical Society (2018)Classical carbenes are usually described as neutral compounds featuring a divalent carbon with only six electrons in their valence shell. It was only in 1988 that our group prepared the first isolable example, in which the ... -
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, ... -
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 ...
