Benign Chlorine-Free Approaches to Organophosphorus Compounds

From rocks to bioactive compounds: a journey through the global P(v) organophosphorus industry and its sustainability

“…The list of pathways presented below is far from exhaustive, and a more curious reader should refer to the few reviews already published on the subject. 188–191…”

Functionalization of Tetraphosphido Ligands by Heterocumulenes

“…The reaction of white phosphorus with transition metal complexes represents a powerful strategy in the synthesis of distinctive phosphorus-based compounds . Transition-metal-mediated P 4 functionalization processes typically involve two principal steps, which have been subject to considerable investigation: Initially, a transition metal complex facilitates the cleavage of one or more P–P bonds of the P 4 tetrahedron, yielding metal complexes that incorporate an activated polyphosphido ligand.…”

Molecular cyclo-P3 complexes of the rare-earth elements via a one-pot reaction and selective reduction

“…1 These metal polyphosphides play an important role as intermediates in the production of organophosphorus compounds since they can circumvent the use of environmentally harmful chlorine gas. 2,3 Starting with the activation of P 4 using transition metals which led to the formation of various polyphosphide ring structures such as [P 4 ] 2− , [P 5 ] − or the neutral [P 6 ]-ring, 1,4–7 this reactivity could be transferred to a variety of main group compounds in the following years. 1,8–14 With the synthesis of [(Cp*) 2 Sm III ) 4 P 8 ] (Cp* = C 5 Me 5 ) by reducing P 4 with the solvent-free [(Cp*) 2 Sm II ], our group successfully isolated the first molecular polyphosphide of the rare earth elements in 2009 (Fig.…”
