Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， name: Sodium trifluoromethanesulfonate, Which mentioned a new discovery about 2926-30-9
Experimental basicities of some of the strongest superbases ever measured (phosphonium ylides) are reported, and by employing these compounds, the experimental self-consistent basicity scale of superbases in THF, reaching a pKalpha (estimate of pKa) of 35 and spanning more than 30 pKa units, has been compiled. Basicities of 47 compounds (around half of which are newly synthesized) are included. The solution basicity of the well-known t-Bu-N=P4(dma)9 phosphazene superbase is now rigorously linked to the scale. The compiled scale is a useful tool for further basicity studies in THF as well as in other solvents, in particular, in acetonitrile. A good correlation between basicities in THF and acetonitrile spanning 25 orders of magnitude gives access to experimentally supported very high (pKa > 40) basicities in acetonitrile, which cannot be directly measured. Analysis of structure-basicity trends is presented.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 2926-30-9, help many people in the next few years.name: Sodium trifluoromethanesulfonate
