The 13C NMR spectra of forty-six cyclic dithioacetals and their derivatives have been studied. A set of shift parameters was established for each of these heterocycles as substituent. Based on the Hammett type correlation for substituted benzenes, the σP +values of cyclic dithioacetal groups ...
The 13C NMR chemical shifts and spin-lattice relaxation times for diphenyl disulfide, diselenide and ditelluride have been measured and assigned. The shielding effects experienced by the carbon atoms re qualitatively discussed in terms of the inductive and mesomeeric properties of the dichalcogen group...

3e, trace WT), which forms by amidation between SNAC-N1 and 3-HAA, as confirmed by LC-high resolution mass spectrometry (LC-HRMS) and nuclear magnetic resonance (NMR) spectroscopy (Supplementary Figs. 19a–c, 29). The accumulation of 2, the hydrolysis product, was also observed. The ...
Internal frequency stabili- zation of the spectrometer was porvided by a lock signal from benzene-d6 used as the solvent. The peak area ratio was determined by the use of a du Pont 310 curve resolver. RESULTS AND DISCUSSION We reported already that 1H NMR spectra of poly(propylene oxide-...
