Abstract:
Transition‐metal mediated white phosphorus activation is of high interest as an ecological alternative to P 4 chlorination pathway to the practically useful phosphorus products. Herein, we report a facile approach for P 4 activation, transformation and subsequent functionalization using cobalt complexes bearing PNP ligands. The use of N , N ‐bis(diphenylphosphino)amine as a ligand allows one to transform P 4 tetrahedron into a zig‐zag chain with the formation of complex [Co(Ph 2 PNHP(Ph 2 ) PPPP P(Ph 2 )NHPPh 2 )]BF 4 ( 4 ). The presence of organic substituent at nitrogen atom in PNP ligand enables one to obtain complexes with η 1 ‐coordinated P 4 molecule, which indicates a crucial role of N−H bond in transformation of white phosphorus tetrahedron. Additionally, complex 4 can readily be functionalized by means of the reaction with Ph 2 PCl leading to the formation of a new complex bearing unique P 9 ‐ligand. The obtained results provide opportunities for facile construction of new polyphosphorus ligands in the coordination sphere of transition metal complexes.
