摘要：

Vinyllithium crystallizes with one equivalent of tetrahydrofuran (thf) and is tetrameric in the solid state whereas in thf solution a tetramer-dimer equilibrium (8:1, 2.0 mol dm-3, -90-degrees-C) is present; lithium-hydrogen distances in solution are derived quantitatively by Li-6-H-1 HOESY with ca. 0.2 angstrom accuracy.
