This thematic issue encompasses diverse aspects of organophosphorus chemistry, an important field within organic chemistry. Well-known examples of organophosphorus compounds include phosphine oxides, phosphinates, and phosphonates, which are widely used as starting materials, intermediates, reagents, and P-ligands in transition metal catalysis or as organocatalysts, and even as solvents (ionic liquids). The relevance of this discipline is further highlighted by a series of famous named reactions applying different P-reactants that form an important toolbox in synthetic organic chemistry regarding P-functionalization.

As such, the scope of this interdisciplinary thematic issue spans from theoretical aspects (mechanisms, stereostructures, as well as conformations) to synthetic methods and useful applications, which all present challenging fields. This may include original methods to prepare important chiral organophosphorus compounds by enantioselective approaches or resolution, P-heterocyclic chemistry, green organophosphorus chemistry, and biologically active substrates, to name but a few examples.
