Synthesis and structural characterization of the nitrosylcobalt complex Co(NO)2[PhP(OCH2CH2)2NH]Cl: a novel carbon dioxide carrier

Aminotroponiminates as Ligands for Potential Metal-Based Nitric Oxide Sensors

“…The appearance of these NO stretching bands indicates the formation of dinitrosyl complexes, examples of which display symmetric and asymmetric stretching modes between 1750-1798 and 1820-1876 cm -1 . [53][54][55][56][57][58][59][60] In addition to the similarity of our ν NO bands to those in these examples, they are suggestive of those at 1809 and 1730 cm -1 for the nondansylated parent complex, [Co(NO) 2 (i-Pr 2 ATI)] (21). The shift to higher energy in the spectra of 20a-c is expected owing to the electron-withdrawing sulfonamides of the DATI ligands.…”

On the Existence of the Elusive Monomethyl Ester of Carbonic Acid [CH3OC(O)OH] at 300 K: 1H‐ and 13C NMR Measurements and DFT Calculations

“…[7] In the course of our research on carbon dioxide chemistry, we have synthesized and characterized the first examples of the elusive species 2. [1,2] We wish to report here the first evidence of the existence of CH 3 OC(O)OH at room temperature and describe its reactivity. Density functional calculations have also been carried out to provide a rationale for our experimental findings.…”

“…The X-ray structure shows the existence of H-bonding through the carboxylic moieties [R = C 6 H 5 CH 2 , RЈ = H; or R,RЈ = PhP(OCH 2 CH 2 ) 2 ]. [1,2] For 3 only a report of its low-temperature IR spectrum can be found in the literature; [3] no report of its existence at room temperature or information tions are examined on the basis of density functional calculations. For kinetic and thermodynamic reasons CH 3 OC(O)OH is unlikely to be formed by insertion of CO 2 Despite their instability, compounds 1-3 are often proposed to be intermediates in reactions in which carbon dioxide is implied.…”

[(TMEDA)Co(NO)2][BPh4]: A versatile synthetic entry point to four and five coordinate {Co(NO)2}10 complexes

“…More recently Lippard and co-workers have reported not only a four coordinate dinitrosyl) cobalt complex supported by an amino (tropiminate) ligand in the context of nitric oxide sensing but also [13,4c]. In addition to these studies, a number of phosphine stabilized mono-halide dinitrosyl complexes have been reported [14,15] [16], characterization data on the latter complex did not include an Xeray diffraction study.…”
