The ring opening of the cyclopropylallylithium compounds 19 and 34 to give the α-durylhomoallyllithium compounds 20 has been shown to proceed at -107°C with ≥90% of stereochemical purity. The resulting α-durylthioalkyllithium compounds are configurationally stable at that temperature. They racemize at -78°C with a half life of 90 min.
