Eitzinger A, Reitz J, Antoni P, Mayr H, Ofial A, Hansmann M
Angew Chem Int Ed Engl . 2023 Aug; 62(40):e202309790. PMID: 37540606
A series of mesoionic, 1,2,3-triazole-derived N-heterocyclic olefins (mNHOs), which have an extraordinarily electron-rich exocyclic CC-double bond, was synthesized and spectroscopically characterized, in selected cases by X-ray crystallography. The kinetics of...

Li L, Mayer R, Stephenson D, Mayer P, Ofial A, Mayr H
Chemistry . 2022 Jun; 28(55):e202201376. PMID: 35758555
Kinetics and mechanism of the reactions of methyl diazoacetate, dimethyl diazomalonate, 4-nitrophenyldiazomethane, and diphenyldiazomethane with sulfonium ylides and enamines were investigated by UV-Vis and NMR spectroscopy. Ordinary alkenes undergo 1,3-dipolar...

Li L, Mayer P, Stephenson D, Ofial A, Mayer R, Mayr H
Angew Chem Int Ed Engl . 2022 Jan; 61(12):e202117047. PMID: 35023245
Methyl diazoacetate reacts with 1-(N-pyrrolidino)cycloalkenes to give products of 1,3-dipolar cycloadditions and azo couplings. The kinetics and mechanisms of these reactions were investigated by NMR spectroscopy and DFT calculations. Orthogonal...

Maji B, Duan X, Justel P, Byrne P, Ofial A, Mayr H
Chemistry . 2021 May; 27(44):11367-11376. PMID: 34002899
Rate constants for the reactions of dialkyl chalcogenides with laser flash photolytically generated benzhydrylium ions have been measured photometrically to integrate them into the comprehensive benzhydrylium-based nucleophilicity scale. Combining these...

Giese B, Mayr H, Reissig H
Angew Chem Int Ed Engl . 2020 Jul; 59(30):12228-12232. PMID: 32627904
Rolf Huisgen would have celebrated his 100th birthday this year. Three of his academic progeny look back on Huisgen as a person, teacher, and scientist. They underline his leading role...
