A new bulky iminophosphonamide as an N,N'-chelating ligand: synthesis and structural characterization of heteroleptic group 13 element complexes.
A sterically demanding iminophosphonamine ligand [(2,6-iPr2C6H3N)P(Ph2)(NtBu)]H (LH) and its lithium derivative [(2,6-iPr2C6H3N)P(Ph2)(NtBu)](Li·2THF) (1) were used to prepare complexes of group 13 elements. The reaction of LH with AlH3·NMe2Et and AlMe3 respectively, affords [LAlH2]2 (2) and LAlMe2 (3). The lithium derivative 1 when treated with the MCl3 compound of group 13 yields [(2,6-iPr2C6...
متن کاملChelating materials immobilizing carboxymethylated pentaethylenehexamine and polyethyleneimine as ligands.
This article presents an overview of our recent progress on the development of chelating materials. Carboxymethylated pentaethylenehexamine (CM-PEHA) and polyethyleneimine (CM-PEI) as chelating ligands show excellent performance for the solid-phase extraction of trace elements. Chelating resins immobilizing these ligands can be readily prepared by immobilizing PEHA and PEI on methacrylate resin...
متن کاملThe study of intermolecular energy transfers in electronic energy quenching for molecular collisions N2-N2, N2-O2, O2-O2
Contributions of intermolecular electron energy transfers in the electronic quenching are calculated for molecular collisions N2(A6 u , W 1u)+N2(X6 g , v=0), N2(A6 u )+N2(X 16+ g , v≥0), N2(A 36+ u )+O2(X 36− g , v=0– 2), O2(a1g , b16+ g )+O2(X 36− g , v=0–2). The calculation has allowed one to estimate the product branching ratios. It is shown that there is a dependence of the calculated rate ...
متن کاملHydrothermal synthesis of Group 13 metal trifluoride complexes with neutral N-donor ligands.
The reactions of the hydrated Group 13 fluorides, MF3·3H2O (M = Al, Ga or In) with 2,2':6',2''-terpyridyl, 2,2'-bipyridyl or 1,10-phenanthroline under hydrothermal conditions (180 °C/15 h) produced high yields of the complexes [MF3(terpy)]·3H2O, [MF3(bipy)(OH2)]·2H2O and [MF3(phen)(OH2)]. X-Ray crystal structures of [M'F3(terpy)]·3H2O (M' = Al or Ga), [M'F3(bipy)(OH2)]·2H2O and [GaF3(phen)(OH2)...
متن کاملSynthesis of chelating bidentate and tridentate cyano ligands and their complexes with Group VII metal carbonyls
Two new bidentate cyano ligands, DiCN-3 (2) and DEN-4 (3) (a,w-bis(2-cyanophenoxy)propane and butane, respectively), have been prepared. These ligands and the ethane analogue DEN-2 (1) react with Mn(C0)5Br to afford complexes of the composition Mr~(cO)~(DicN-n)Br (n= 2, 9; n = 3, 10; n = 4, 11). Complexes 9 and 10 appear to be mononuclear and contain 13and 14-membered chelate rings, respectivel...
