Application
- Lithium acetylide, ethylenediamine complex is a general reagent to synthesize ethynylated ketones.
- It is used as a ligand in the coordination chemistry to synthesize transition metal complexes such as 1-alkynyl-dimethyl(triorganophosphine)gold(III) complex.
- It is employed in the ring opening reaction of epoxides, as in the total synthesis of (−)-goniotrionin and englerin A.
- It can also be used in the ethynylation of alkyl halides to prepare terminal alkynes.
