Witryna11 mar 2005 · Addition of 2 equiv of THF to toluene solutions induces the formation of the same THF solvated 1:1 dimer as observed in neat THF. NMR evidence suggests that in THF the mixed aggregate has close contact between the olefin and the β-CH 2 of nBuLi, while in the absence of THF, the allyl chain appears to be pointed away from the … Witryna11 sty 2024 · THF is a solvent that contains carbon, hydrogen, and one oxygen atom. Although it certainly has its drawbacks and limitations, what we will see is that, like any organic solvent, it serves an ...
