Gradiski, Matthew V.;Kharat, Ali Nemati;Ong, Maegan S. E.;Lough, Alan J.;Smith, Samantha A. M.;Morris, Robert H. research published 《 A One-Step Preparation of Tetradentate Ligands with Nitrogen and Phosphorus Donors by Reductive Amination and Representative Iron Complexes》, the research content is summarized as follows. The synthesis and use of the first examples of unsym., mixed phosphine donor tripodal NPP2‘ ligands N(CH2CH2PR2)2(CH2CH2PPh2) are presented. The ligands are synthesized via a convenient, one pot reductive amination using 2-(diphenylphosphino)ethylamine and various substituted phosphonium dimers in order to introduce mixed phosphine donors substituted with P/P’, those being Ph/Cy (2), Ph/iPr (3), Ph/iBu (4), Ph/o-Tol (5), and Ph/p-Tol (6). Addnl., authors have developed the first known synthesis of a sym. tripodal NP3 ligand N(CH2CH2PiBu2)3 using bench safe ammonium acetate as the lone nitrogen source (7). This new protocol eliminates the use of extremely dangerous nitrogen mustard reagents typically required to synthesize NP3 ligands. Some of these tetradentate ligands and also P2NN’ ligands N(CH2-o-C5H4N)(CH2CH2PR2)2 (P2NN’-Cy, R = Cy; P2NN’-Ph, R = Ph) prepared by reductive amination using 2-picolylamine are used in the synthesis and reactions of iron complexes. FeCl2(P2NN’-Cy) (8) undergoes single halide abstraction with NaBPh4 to give the trigonal bipyramidal complex [FeCl(P2NN’-Cy)][BPh4] (9). Upon exposure to CO(g), complex 9 readily coordinates CO giving [FeCl(P2NN’-Cy)(CO)][BPh4] (10), and further treatment with an excess of NaBH4 results in formation of the hydride complex [Fe(H)(P2NN’-Cy)(CO)][BPh4] (11). Their previously reported complex FeCl2(P2NN’-Ph) undergoes double halide abstraction with NaBPh4 in the presence of the coordinating solvent to give [Fe(NCMe)2(P2NN’-Ph)][BPh4]2 (12). Ligand 3 can be coordinated to FeCl2, and upon sequential halide abstraction, treatment with NaBH4, and exposure to an atm. of dinitrogen, the dinitrogen hydride complex [Fe(H)(NPP2‘-iPr)(N2)][BPh4] (13) is isolated. Sym. NP3 ligand 7 can also be coordinated to FeCl2 and, upon exposure to an atm. of CO(g), selectively forms [FeCl(NP3)(CO)][BPh4] (14) after salt metathesis with NaBPh4. Complex 14 can be treated with an excess of NaBH4 to give the hydride complex [Fe(H)(NP3)(CO)][BPh4] (15), which can further be deprotonated/reduced to the Fe(0) complex Fe(NP3)(CO) (16) upon treatment with an excess of KH. The synthesis of novel unsym. tripodal mixed phosphine donor NPP2‘ ligands is reported. These are used to synthesize a range of iron complexes. A sym. tripodal NP3 ligand is made from ammonium acetate and is used to synthesize the first Fe(0) NP3 complex among others.

2-Bromoethylamine hydrobromide is a nonsteroidal anti-inflammatory drug that is used to treat inflammation and pain. It is a prodrug that is hydrolyzed in vivo to its active form, 2-Bromoethylamine hydrobromide. The bound form of this drug has been shown to inhibit the development of cell nuclei in the nucleus of cells. This drug also inhibits the production of nitric oxide, which leads to cell death by necrosis. 2-Bromoethylamine hydrobromide has been shown to have an inhibitory effect on the activity of glycol ethers, which are used as solvents for resins in coatings and adhesives., 2576-47-8.
