| | PROPYNYLLITHIUM Usage And Synthesis |
| Uses | Propynyllithium is a powerful nucleophilic source of the propynyl unit for many electrophiles. | | Preparation | Propynyllithium is prepared in situ under nitrogen by reaction of propyne (condensed into cold THF) with n-Butyllithium in THF at -78 °C or Lithium Amide in ether/liquid ammonia below -50 °C, or by reaction of 1,2-dibromopropane with equiv of Lithium Diisopropylamide (double elimination of hydrogen bromide and deprotonation) at -60 °C to 0 °C in THF. | | Definition | ChEBI: Prop-1-ynyllithium is an alkynyllithium compound. | | storage | Propynyllithium must be prepared and transferred under inert gas (Ar or N2) to exclude oxygen and moisture. |
