Elemental Phosphorus in the Synthesis of Organophosphorus Compounds: The Recent Advances (A Review)
Russian Journal of General Chemistry, 2023
Recent publications on direct reactions of elemental phosphorus with organic halides (alkyl bromides, aryl (and hetaryl) halides, and aryl (and hetaryl) methyl halides) in the presence of superbasic and micellar catalysts are considered. The development of effective, technologically and environmentally acceptable methods for obtaining alkyl(and benzyl)-H-phosphinic and alkylphosphonic acids, triaryl(and hetaryl)phosphines and hetarylmethylphosphine oxides based on the above reactions is analyzed.

The direct incorporation of the Group15 elements into transition-metal complexes may be a useful way to utilize these materials for further elaboration.[1] The two lightest elements of this group are nitrogen and phosphorus, both of which are essential to all life on this planet, but in their elemental forms can be deadly. For example, elemental nitrogen occurs as N2, which, in its gaseous form, cannot support aerobic life, and one of the allotropes of phosphorus, P4, is a severe bone toxin.[2] While activation of dinitrogen is difficult ...

Rhodium-Mediated Functionalization of White Phosphorus: A Novel Formation of C−P Bonds
Organometallics
The rhodium alkyl and aryl complexes [(triphos)Rh(R)(η 2-C 2 H 4)] (R) Me (1), Et (2), Ph (3); triphos) MeC(CH 2 PPh 2) 3) react with white phosphorus in THF at room temperature to give the new complexes [(triphos)Rh(η 1 :η 2-P 4 R)] (R) Me (4), Et (5), Ph (6)). This reaction represents the first example in which a P-C bond is formed by starting from white phosphorus through the mediation of a transition-metal complex. Chemical reactions resulting in the cleavage of C-P bonds are rather common processes which are often promoted by transition-metal complexes. 1 In contrast, the reverse reaction, in which a P-C bond is formed through the intermediacy of a d-block metal, is a very rare process, notwithstanding the ubiquitous role played by phosphines and by phosphorus compounds in both organometallic and coordination chemistry. 2 Examples of metal-mediated P-C bond-forming reactions are limited to the interchange reaction between phosphorus-bound aryl moieties and palladium-bound aryl or alkyl groups, 3 to the Pd-catalyzed coupling of aryl halides with silyl-or stannylphosphines, 4 and to the recently reported catalytic hydrophosphorylation of alkynes 5 and hydrophosphination of olefins. 6 In both of the catalytic processes, the P-C bond-forming step is considered to follow the insertion of the unsaturated substrate into the M-P bond. Despite the fact that the coordination chemistry of white phosphorus is rich and has been extensively investigated, 7 metal-promoted P-C bond formation starting from white phosphorus is still unknown. 8 This process, however, would be highly desirable, due to the need for an environmentally more acceptable technology for the preparation of organophosphorus compounds. 9,10
