资源简介：
The
solid-state structures of unsolvated, hexameric cyclopentyllithium
and tetrameric cyclopentyllithium tetrahydrofuran solvate were determined
by single-crystal X-ray diffraction. Cyclopentyllithium easily crystallized
in hydrocarbon solvents. Solution-state structural analyses of cyclopentyllithium
and cyclopentyllithium–tetrahydrofuran complexes in toluene-d8 were also carried out by diffusion-ordered
NMR spectroscopy with diffusion coefficient–formula weight
correlation analyses and other one- and two-dimensional NMR techniques.
The solution-state studies suggest that unsolvated cyclopentyllithium
exists as hexamer and tetramer equilibrating with each other. Upon
solvation with tetrahydrofuran, cyclopentyllithium exists mostly as
a tetrahydrofuran tetrasolvated tetramer.
