TL;DR: The effect of substituents at the silicon atom and in the side chain as well as those of the solvent and temperature on the strength of the intramolecular Si ← O bond in molecules of (aroyloxymethyl)trifluorosilanes and their analogs have been investigated by 1H, 19F and 29Si NMR spectroscopy as discussed by the authors.

TL;DR: In this paper, a trimeric structure and an intramolecular dynamic process are proposed for alkyl- and phenyl-stannatranes with NMR data for 1H, 13C, 15N and 119Sn.

TL;DR: In this paper, single and dual substituent parameter analysis was performed for a series of meta and para substituted phenoxytrimethylsilanes and the results showed that the increased silicon shift sensitivity to substituents in phenoxysilanes is due to higher sensitivity of silicon shielding (ϱ shield ) to electron density in these compounds rather than to a bettr transmission of electronic effects.

TL;DR: The low temperature 19 F NMR spectra of RS(O)CH 2 CH 2 Sif 3 (R = CH 3, C 2 H 5 or C 6 H 5 CH 2 ) display a non-equivalence of all the fluorine atoms in their molecules, due to both the trigonal-bipyramidal structure of the silicon atom involved in the intramolecular Si←O coordination and the chirality of the sulfur atom as mentioned in this paper.

TL;DR: The 13C NMR spectra of some 2-arylimidazo-[4,5-c]- and -[4, 5-b]-pyridines and their protonated forms have been studied as mentioned in this paper.
