Interaction of hydrated protons with octyl-phenyl-N,N-diisobutylcarbamoylmethyl phosphine oxide (CMPO): NMR and theoretical study
Original language description
Interaction of octyl-phenyl-N,N-diisobutylcarbamoylmethylphosphine oxide (CMPO, the classical' rare metal extn. agent) with fully ionized hydrated protons (HP) was studied in acetonitrile-d3 using 1H, 13C, 31P NMR, PFG NMR and magnetic relaxation. The exptl. results were confronted with high-precision ab initio DFT calcns. Relative chem. shifts of NMR signals of CMPO (0.01 mol/L) under the presence of HP in the molar ratio ? = 0-2.0 mol/mol show binding between CMPO and HP. Self-diffusion measurements using 1H PFG NMR demonstrate that larger complexes with higher content of CMPO are generally formed at ? { 0.75. Analyzing the collective dependence of 13C and 31P NMR chem. shifts on ? by the use of program LETAGROP, we obtained very good fitting for theassumed coexistence of two complexes (CMPO)2?HP (C2) and CMPO. The logarithms of the resp. stabilization consts. log Ki were found to be 7.518 (C2) and 4.581 (C1).
