In addition, the observed selectivity of the oxidative coupling reaction is related to the electronic structure of the TABs through quantum-chemical calculations and experimental

An interrupted Pummerer/nickel‐catalysedcross‐coupling strategy has been developed and used in the elaboration of styrenes. The operationally simple method can be carried out as a one‐pot process, involves the direct formation of stable alkenyl sulfonium salt intermediates, utilises a commercially available sulfoxide, catalyst, and ligand, operates at ambient temperature, accommodates sp‐, sp2‐, and

The Negishi coupling reaction between arylzinc halide reagents and 11CH3I has been used to synthesise 11C-methylated arene species via a palladium-mediated process. The metabotropic glutamate receptor subtype-5 radiotracer [11C]MPEP has been radiolabelled using this technique.

We report a Ni-catalyzed regioselective alkylarylation of vinylarenes with alkylhalides and arylzinc reagents to generate 1,1-diarylalkanes. The reaction proceeds well with primary, secondary and tertiary alkylhalides, and electronically diverse arylzinc reagents. Mechanistic investigations by radical probes, competition studies and quantitative kinetics reveal that the current reaction proceeds
