Notes:
The solvation and ion pair nature of α-(phenylthio)benzyllithium (2d) in THF solution were investigated by NMR-spectroscopic methods. The effect of additives such as diethylene-glycol dimethyl ether or of 12-crown-4 was studied. The results were compared to those of benzyllithium compounds 4 and 6, containing a pentaoxapentadecane ansa chain. These compounds exist as contact ion pairs in which lithium is held at the anionic carbon. This is reflected in the 6Li,13C coupling and 1H,6Li-HOESY contacts in the NMR spectra.
