Efficient large-scale synthesis of 9-alkylfluorenyl phosphines for Pd-catalyzed cross-coupling reactions
The reactions of aliphatic alcohols with fluorene coupled with a transfer hydrogenation result in the facile formation of 9-alkylfluorenes, whose deprotonation with nBuLi and quenching of the fluorenyl anion with Cy 2PCl in MTBE gave 9-alkylflu
