Organophosphorus Synthesis and Catalysis

Organophosphorus chemistry underpins a vast array of applications, from ligand design in homogeneous catalysis to materials science and medicinal chemistry. Central to this field is the formation and manipulation of phosphorus–carbon and phosphorus–heteroatom bonds, enabling fine control over electronic and steric properties. Modern approaches span radical, photochemical and transition-metal-catalysed pathways, often employing interelement phosphorus reagents to generate reactive intermediates under mild conditions. Advances in computational screening and mechanistic insight have driven the rational design of novel diphosphine and multifunctional ligands, while developments in hemilabile frameworks have enhanced catalyst turnover and selectivity. Together, these innovations support sustainable syntheses of agrochemicals, pharmaceuticals and organometallic catalysts with improved efficiency and reduced environmental impact.

Research from Nature Portfolio

Recent studies have refined radical-based strategies for constructing diphosphine ligands directly from simple feedstocks. A theory-driven approach harnessed computational reaction-path algorithms to guide the radical difunctionalisation of ethylene, yielding both symmetric and unsymmetric 1,2-bis(diphenylphosphino)ethane analogues. This methodology provides access to bidentate ligands with finely tuned electronic and steric profiles, which coordinate to a range of transition-metal centres. The unsymmetric variants exhibit distinct reactivity patterns compared with their symmetric counterparts, demonstrating the power of radical pathways combined with quantum-chemical design for bespoke catalyst development.

Technical terms

Diphosphine ligand: A bidentate ligand with two phosphorus donor sites linked by an organic backbone, commonly used to stabilise transition-metal complexes.

Radical difunctionalisation: A synthetic strategy in which two functional groups are simultaneously installed onto a substrate via radical intermediates.

Interelement compound: A reagent containing a heteroatom–heteroatom single bond (e.g., P–P or P–S) that, upon activation, generates heteroatom-centred radicals.

Hemilability: The reversible coordination of one donor arm of a multidentate ligand, providing alternate free coordination sites on the metal centre during catalysis.
