A four-membered heterocyclic prevented biradical that can be described as a zwitterion or masked N-heterocyclic phosphinidene
Autor: Tim Suhrbier, Jonas Bresien, Alexander Villinger, Axel Schulz
Publikováno v: Cell Reports Physical Science, Vol 3, Iss 3, Pp 100777- (2022)
Summary: Heterocyclobutane-1,3-diyls bridge the gap between organic and inorganic chemistry and are known for the majority of group 13–15 elements. The kinetically stabilized compounds have been employed in the activation of small molecules, akin t

Coinage metal complexes of multidentate Pacman phosphane ligands
Autor: Leon Ohms, Liesa Eickhoff, Pascal Kramer, Alexander Villinger, Jonas Bresien, Axel Schulz
Publikováno v: Chemical Communications. 59:5245-5248
A new way to play “Pac-Man™”: We have synthesized two different Pacman phosphanes as a new kind of multidentate phosphane ligands and used them to complex coinage metals.

Concerted addition of aldehydes to the singlet biradical [P(μ-NTer)]2
Autor: Jan Rosenboom, Alexander Villinger, Axel Schulz, Jonas Bresien
Publikováno v: Dalton Transactions. 51:13479-13487
The cycloaddition of aldehydes to the singlet biradical [P(μ-NTer)]2 is demonstrated experimentally. High-level ab initio calculations reveal a minimal electronic activation barrier.

A cyclic thioketone as biradical heterocyclopentane-1,3-diyl: synthesis, structure and activation chemistry
Autor: Henrik Beer, Alexander Linke, Jonas Bresien, Alexander Villinger, Axel Schulz
Publikováno v: Inorganic Chemistry Frontiers. 9:2659-2667
Reaction of [(μ-NR)P˙]2 with CSCl2 and Mg gives a deep blue, highly labile cyclic thioketone with singlet biradical character. It can be converted to a housane-type isomer by light and to bicyclic cage compounds by addition of CS2 and benzaldehyde.

Lewis Acid-Catalyzed Carbofunctionalization of Uncommon C,N-Diacyliminium Ions: Controlling Regio- and Enantioselectivity
Autor: Alexander Villinger, Mario Frahm, Lisa Marie Gronbach, Dirk Michalik, Malte Brasholz, Alice Voss, Jonas Bresien
Publikováno v: Organic Letters. 23:7834-7838
The tricyclic azepino[1,2-a]indole acetates 7, readily accessible by visible-light-driven catalytic photooxygenation of cyclohepta[b]indoles 1, are convenient precursors to novel and uncommon cyclic C,N-diacyliminium ions 3. We report here the first
