摘要：

What affects the configurational stability of chiral organolithium reagents? It is frequently proposed that ion pair separation plays a key role in the configurational inversion of alkyllithium compounds. But NMR studies of 1 and 2 show that the configurational stability of the solvent‐separated ion pair is greater than that of the contact ion pair. (Figure Presented.)
