Symmetric coupling of a hardly forming multifunctional diazonium salt of low basicity melamine with phenols is performed with difficulty with a very slight decline in the higher phenol acidity. The azopyrogallol derivative maintains the melamine D3h symmetry explicit in the 1H-NMR spectrum showing the...
the same day, using exactly the same acquisition parameters as for the spectrum of the studied sample. The same processing was applied to both spectra and the integrals were determined by deconvolution (best-fit analysis). Details on the titration experiments and on the deconvolution analysis are ...
Reichardt's dye, 2,6-diphenyl-4-(2,4,6-triphenyl-1-pyridinio)phenolate (1), has a very large negative solvatochromism in the long wavelength absorption in the UV–vis spectrum when going from nonpolar to polar solvents. This shift provides the basis of the important and widely used E T...
Figure 3. Contour plot of the 500 MHz CP55,940 NOESY spectrum in CDCI3. The NOE interactions for CP55,940 are indicated with arrows. The full analysis of NOESY and DQF-COSY spectra of other analogues, plus computational studies, further showed that this was typical for all congeners of ...
