Technology Process of nido-(Et)2C₂B₄H₆

There total 1 articles about nido-(Et)2C₂B₄H₆ 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: 74.0%

pentaborane(9) + hex-3-yne (928-49-4) → nido-(Et)2C2B4H6 (80583-48-8) + triethylamine-borane (1722-26-5)

Guidance literature:

With triethylamine; In tetrahydrofuran; soln. of borane in THF syringed onto 3-hexyne (-65°C, under N2), slowly warmed to room temp. , addn. of triethylamine (at room temp.), stirred (several days), monitored by (11)B NMR; repeated trap-to-trap distn., carborane remaining in the 0°C trap;

Reference yield: 100.0%

dimethylacetylene (503-17-3) + 1,2-diethyl-nido-carborane (80583-48-8) → nido-4,5-Me2-7,8-Et2C4B4H4 + butene-2 (107-01-7) + carbon monoxide (201230-82-2)

Guidance literature:

nonacarbonyltris(triphenylphosphine)triruthenium; In toluene; Reaction mixture is heated in an oil bath at 140°C for 10 min., frozen at -196°C and degassed, and heated at 140°C for 24 h.; vacuum fractionation through a -23, -95, -196°C trap series stopped Me2Et2C4B4H4 (-23°C) and butene (-196°C); GLC;
