Bidentate organophosphorus ligands formed via P–N bond formation: synthesis and coordination chemistry

Experimental and Theoretical Investigations of the Contact Ion Pairs Formed by Reactions of the Anions [(EPR2)2N]− (R = iPr, tBu; E = S, Se) with the Cations [(TePR2)2N]+ (R = iPr, tBu)

“…The primary focus has been the coordination chemistry of these bidentate ligands, and several reviews that provide details of the complexes of 1 with a diverse array of main group, lanthanide and transition metals have been published. [3][4][5] A significant recent application of these complexes, particularly in the case of the selenium derivative (1, E = Se, R = i Pr), has been as single-source precursors for the generation of metal selenides in the form of semiconducting thin films [6][7][8][9][10][11][12][13][14][15][16][17] or quantum dots 18 via CVD or solvothermal processes.…”

TetramethylN,N′-(2,2,3,3,4,4-hexafluoro-1,5-dioxopentane-1,5-diyl)bis(phosphoramidate)

“…There has recently been a resurgence of interest in their coordination chemistry as a consequence of the steric control that this ligand system may impart compared to, for example, β -diketonates. The wide range of coordination compounds were synthesized and described in detailes (Ly & Woollins, 1998).…”

Oxidation State of Cobalt in the Coordination Compounds with N-(Thio)phosphorylated Acylamidophosphinates in Solutions

“…The presence of coordination-active (thio)carbonyl and (thio)phosphoryl groups and of a relatively acidic proton in the molecules of N-(thio)phosphorylated (thio)ureas and (thio)amides predetermines the possibility of chelating coordination of these ligands through the sulfur and oxygen donor centers with the formation of a stable six-membered chelate ring [3,4]. The oxidation state of the central ion, in particular, of the cobalt ion, in such complexes previously seemed doubtless and hence was not evaluated.…”
