Webb19 juni 2024 · For solvent-free CpLi, the computed Li + chemical shift is −8.55 ppm. For solvated CpLi (THF) x (x = 1–3), the computed Li + chemical shift is −8.81, −7.77 and − 6.04 ppm, and this indicates that solvent coordination plays an important role in calculating the Li + chemical shift.
