Description and Uses

• 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.
