The Pentafluorophenyl Cation: A Superelectrophile and Diradical

Angewandte Chemie, EarlyView.
From radical to diradical cation. Photoionization (PI) of the thermally generated pentafluorophenyl radical yields the pentafluorophenyl cation in the gas phase. This cation is found to be a diradical with nearly degenerate open‐shell singlet and triplet ground states, and it is even more unstable than the parent phenyl cation by ∼40 kcal mol−1 ...

Are Grignard Reactions in Deep Eutectic Solvents Interface‐Driven?

Angewandte Chemie, EarlyView.
Experimental and molecular dynamics studies of acetophenone, alongside a computational analysis of i‐PrMgCl in a biphasic ChCl:2Gly DES/THF solution, offer valuable insights into the remarkable efficiency of the Grignard reaction under these conditions.

Synthesis and Application of Bioactive N‐Functionalized Aziridines

Angewandte Chemie, EarlyView.
This review discusses modern synthetic methods for the preparation of aziridine‐containing small molecules, including biocatalytic, electrocatalytic, and photocatalytic strategies. We highlight the compatibility of various synthetic methods with control of the exocyclic N‐substituent.

Iron‐Catalyzed trans‐Hydrostannation of Terminal Alkynes

Angewandte Chemie, EarlyView.
An easily accessible and cheap iron complex is capable of catalyzing highly regio‐ and stereoselective trans‐hydrostannation reactions of terminal alkyl alkynes as well as the stannylative cyclization of 1,6‐enynes. The addition likely follows a “modified Chalk–Harrod” mechanism; the intervention of iron vinylidene intermediates can be excluded ...
