On the configurational stability of α-bromo-alkyllithium compounds
Abstract
1-Bromopentyllithium 1, a typical [bromocarbenoid,] has been established to be chiral and configurationally stable at –120 °C by a test based on kinetic resolution; likewise, diastereoisomeric 1-bromoalkyllithium compounds were generated from the bromo-tin compounds 5 and 6 and found to be configurationally stable at –110 °C.
