A test based on kinetic resolution has been applied to the α-bromo-, α-phenylseleno- and α-phenylthio-alkyllithium compounds 1, which shows that addition of these species to the chiral aldehyde 6 occurs faster than enantiomer equilibrium of the organolithium compounds. - Keywords: Configurational Stability; Organolithium Compounds

Using a test based on kinetic resolution the α-phenylseleno-alkyllithium compounds 3 have been shown to undergo, enantiomer equilibration at -105°C with a rate comparable to that of their addition to aldehydes. At -125°C in Me-THF as solvent, the α-phenyl
