Lemieux‐Johnson oxidation with N,N‐bidentate bisPYA ruthenium complexes: insights into reaction conditions and catalyst design
Autor: Dr. Kevin Salzmann, Dr. Candela Segarra, Dr. Aline Carrel, Prof. Dr. Martin Albrecht
Publikováno v: ChemistryEurope, Vol 2, Iss 2, Pp n/a-n/a (2024)
Abstract The carbonyl group is arguably the most versatile functional group for synthetic purposes. Here, a series of N,N’‐bis(pyridylideneamide) (bisPYA) complexes of ruthenium(II), [Ru(cym)(bisPYA)Cl]+ (cym=cymene), were synthesized and applied

Donor-Flexible Bis(pyridylidene amide) Ligands for Highly Efficient Ruthenium-Catalyzed Olefin Oxidation
Autor: Kevin Salzmann, Candela Segarra, Martin Albrecht
Publikováno v: Angewandte Chemie (International ed. in English). 59(23)
An exceptionally efficient ruthenium-based catalyst for olefin oxidation has been designed by exploiting N,N'-bis(pyridylidene)oxalamide (bisPYA) as a donor-flexible ligand. The dynamic donor ability of the bisPYA ligand, imparted by variable zwitter

[EN] Two different heterogeneous catalysts carrying aryl-sulfonic moieties, in which the aromatic ring was either fluorinated or not, were successfully synthesized. The multi-step synthetic approaches implemented involved the synthesis of the silyl-d

Mesoionic and Related Less Heteroatom-Stabilized N-Heterocyclic Carbene Complexes: Synthesis, Catalysis, and Other Applications
Autor: Candela Segarra, Ángela Vivancos, Martin Albrecht
Publikováno v: Chemical reviews. 118(19)
Mesoionic carbenes are a subclass of the family of N-heterocyclic carbenes that generally feature less heteroatom stabilization of the carbenic carbon and hence impart specific donor properties and reactivity schemes when coordinated to a transition

Publikováno v: Organometallics. 34:4076-4084
A ruthenium cymene complex bearing a bidentate ligand composed of the N-mesoionic donor N-[1-methylpyridin-4(1H)-ylidene]amide and the C-mesoionic donor 1,2,3-triazolylidene was prepared. Spectroscopic analyses including UV–vis, electrochemical, an

Thermolysis of Rh(PPh3)4H in the presence of the six-membered N-heterocyclic carbene 1,3-bis(2-propyl)-3,4,5,6-tetrahydropyrimidin-2-ylidine (6-iPr) gave the monocarbene complex Rh(6-iPr)(PPh3)2H as a 1:2 mixture of the cis- and trans-phosphine isome

Palladium Catalysts with Sulfonate-Functionalized-NHC Ligands for Suzuki−Miyaura Cross-Coupling Reactions in Water
Autor: Fernando Godoy, Eduardo Peris, Candela Segarra, Macarena Poyatos
Publikováno v: Organometallics. 30:684-688
Four new Pd(II) complexes containing sulfonate-functionalized N-heterocyclic carbene ligands have been synthesized. All new complexes are palladium bis-NHCs, in which the ligands adopt a monodentate, bis-chelating, and pincer coordination form, so th
