General description
Toluene-d8 is a deuterated NMR solvent. It is an anhydrous solvent, which minimizes any interference from water peaks. It is useful in performing critical air- and moisture-sensitive NMR analysis. Its spin–lattice relaxation time (T 1), viscosity and density have been measured over -35 to 200°C range. The temperature dependent chemical shifts in the proton NMR spectra of α,β-unsaturated ketones in toluene-d8 has been studied.

The acetate-initiated aliphatic isocyanate trimerization to isocyanurate was investigated by state-of-the-art analytical and computational methods. Although the common cyclotrimerization mechanism assumes the consecutive addition of three equivalents of isocyanate to acetate prior to product formation, we found that the underlying
