The influence of the aprotic Solvents on the 1H NMR spectra of the N-H proton has been studied. The chemical shift shows quite good correlation with the solvatochromic parameters, *, , and ±, while a fair correlation with the Gutmann donor and acceptor numbers were obtained.doi:10.1080/...

2-boryl shift, in which boron migrates as a nucleophile in its tetracoordinate form. The second case involves a neighbouring atom-promoted 1,4-boryl shift, in which boron migrates as an electrophile in its pseudo-tricoordinate form. Density functional theory studies and in situ NMR ...

13C- and 195Pt-NMR. spectra for the complexes trans-PtCl2(amine)(CH2CH2) have been measured. For amine = (S)-N-methyl-伪-methylbenzylamine the two diastereomers present may be distinguished from the values 3J(Pt,C). The 195Pt-chemical shift is shown to be sensitive to subtle ...
Subsequently, in correlation with crystallographic and NMR data [43], MM (MMFF94), semiempirical (MNDO/AM1), and DFT (BP/DN**) methods revealed that the AAF fluorenyl moiety falls 45 or 90 degrees with respect to the adducted G in the nucleobase model, while repulsion between the acetyl...
NMR spectra have also been used for evaluation ofR:Sratio ofSchiff basederivative of 1-phenylethylamine. On the basis of automated peak picking and integration procedure, after less than 2 h, the enantiomeric purity was established.R:Sratio was 34.4:65.6, which is close to the values obtained...
In the following examples, nuclear magnetic resonance (referred to as “1H-NMR”) spectra were obtained using tetramethylsilane for the standard substance, and chemical shift values are indicated with δ values (ppm). Deuterated chloroform (CDCl3) or deuterated dimethyl-sulfoxide (DMSO-d6) was us...
