intermolecular cross‐coupling reactionsIt was found that the polymeric catalyst provides an extra protection of its catalytic copper complexes against water resulting in higher reaction rates than the low-molecular-weight catalyst. A similar stabilizing effect was found against so-called substrate ...

C–H functionalization reactions are playing an increasing role in the preparation and modification of complex organic molecules, including pharmaceuticals, agrochemicals and polymer precursors. In recent years, there have been many reports of radical C–H functionalization reactions initiated by hydrogen-at...
1.3.1 Cross-coupling reactions Cross-coupling reactions occur when two reagents, both with activating groups, react together with a metal catalyst to form a new covalent bond, driven by loss of the activating groups. Iron cross-coupling reactions were first reported in the 1940s by Kharasch and...

Cross-coupling reactions are powerful synthetic tools for the formation of remarkable building blocks of many naturally occurring molecules, polymers and biologically active compounds. These reactions have brought potent transformations in chemical and pharmaceutical disciplines. In this review, we have focuse...
