Unlocking Catalyst Activation as a Critical Bottleneck in Cross‐Coupling Reactions: Room‐Temperature Couplings of Weak Nucleophiles Enabled by [Pd(1‐MeNAP)TFA]2 Precatalysts

Angewandte Chemie International Edition, EarlyView.
In many Pd‐catalyzed cross‐couplings, catalyst performance has been found to be limited by catalyst activation. Methylnaphthyl (MeNAP) palladium trifluoroacetate dimers are presented as easy‐to‐store and easy‐to‐handle precursors, which rapidly activate under reaction conditions, even when only weakly coordinating, non‐reducing nucleophiles are present.

Stabilizing the Hexacyanotrimethylenecyclopropane Electron Acceptor—Structural and Photophysical Characterization

Angewandte Chemie International Edition, EarlyView.
An improved low‐temperature synthesis enables the first comprehensive structural and spectroscopic characterisation of neutral hexacyanotrimethylenecyclopropane (CN6CP). Combined IR/Raman, UV–Vis and ssNMR analyses reveal a deeper understanding of its oxidation‐state‐dependent charge redistribution, σ‐aromaticity of the cyclopropane core, and redox ...
