A Bench‐Stable Fluorophosphine Nickel(0) Complex and Its Catalytic Application

Angewandte Chemie, EarlyView.
We herein present the synthesis of a bench‐stable Ni(0) complex, [Ni(PFPh2)4], stabilized by vastly underexplored fluorophosphine ligands. The application of [Ni(PFPh2)4] in Suzuki–Miyaura and Kumada‐Tamao‐Corriu cross‐coupling reactions as well as in Buchwald–Hartwig C─N bond formation reactions, indicates its promising potential as alternative to ...

Unprecedented “off‐pathway” [2+2] Cycloaddition‐Retroelectrocyclization Reaction Between an Unsymmetric Alkyne and Tetracyanoquinodimethane

Angewandte Chemie, EarlyView.
The widely used [2+2] cycloaddition‐retroelectrocyclization reaction between tetracyanoquinodimethane (TCNQ) and an activated alkyne has been shown to occur with “inverted” regiochemistry to give exclusive formation of an unexpected regioisomer. A combined experimental and theoretical study helped unravel the peculiar reaction mechanism underlying the ...

Facile N═N Bond Cleavage of Cis‐Azobenzene with Bis‐silylenes

Angewandte Chemie, EarlyView.
The unexpectedly easy N═N bond scission of cis‐azobenzene using two bis‐silylenes with different spacers and distinct SiII···SiII distances is reported. While both bis‐silylenes enable C─H and N═N π‐bond activation of trans‐azobenzene, the cooperative disilicon(II)‐mediated activation of cis‐azobenzene leads to bis‐silamines (Si═N) and related novel ...
