Technology Process of Lithium hydrogenacetylide

There total 1 articles about Lithium hydrogenacetylide which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

phenyllithium (591-51-5) + 1,2-dichloro-ethane (107-06-2,52399-93-6) → monolithium acetylide (70277-75-7,1111-64-4) + dilithium acetylide

Guidance literature:

In diethyl ether; reaction of CH2CHCl with Li phenyl in ether, precipitation of Li2C2 and LiHC2;;

Reference yield:

tetrakis(μ-2-anilinopyridinato)dirhodium(II,III) chloride (109532-21-0) + monolithium acetylide (70277-75-7,1111-64-4) → Rh2(2-anilinopyridinate)4(CCH)*CH2Cl2

Guidance literature:

In tetrahydrofuran; under Ar, 30 min at room temp.; removal of solvent, column chromy. (silica gel, CH2Cl2), recrystn. (CH2Cl2/hexane), dried in a vac. oven at 50°C for 2 days; elem. anal.;
