Useful:

• Uses: The largest industrial use of lithium acetylide is in the production of vitamin A. It is used to ethynylate methyl vinyl ketone to produce a tertiary carbinol, an intermediate in the multistep synthesis. A second industrial use is in the production of Placidyl?, a tranquilizer . In this case it is used to ethynylate methyl beta-chloro vinyl ketone. Lithium acetylide is used extensively in the laboratory, mostly for the ethynylation of ketones. Lithium acetylide is not an article of commerce since it is unstable and cannot be shipped. Lithium acetylide ethylenediamine complex is used in the synthesis of a chiral cyclopropanol. It is also used as an alkynylating reagent for the enantioselective alkynylation of ketones catalyzed by lithium binaphtholate without using other metal sources. 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.
