Technology Process of 1-TRIBUTYLSTANNYL-2-TRIMETHYLSILYLACETYLENE

There total 7 articles about 1-TRIBUTYLSTANNYL-2-TRIMETHYLSILYLACETYLENE 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: 90.0%

tributyltin chloride (1461-22-9) + trimethylsilylacetylene (1066-54-2) → (trimethylsilylethynyl)tributyltin (81353-38-0)

Guidance literature:

With n-butyllithium; In tetrahydrofuran; (N2); to a soln. of BuLi the acetylene was added at -78°C, soln. was allowed to warm to 0°C over 0.5 h, metal chloride was slowly added, after stirring at -78°C for 0.5 h, the mixt. was warmed up to room temp. and stirred; the mixt. was quenched with water and extd. 3 times with ether, the combined organic phases were dried over MgSO4 and filtered, solvent was removed under reduced pressure, distillation;

Reference yield: 87.0%

tri-n-butyl-tin hydride (688-73-3) + trimethylsilylacetylene (1066-54-2) → (trimethylsilylethynyl)tributyltin (81353-38-0)

Guidance literature:
