Technology Process of Bis(tributylstannyl)acetylene

There total 12 articles about Bis(tributylstannyl)acetylene 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: 64.0%

tributyltin methoxide (1067-52-3) + 2-methyl-but-3-yn-2-ol (115-19-5) → bis(tributylstannyl)acetylene (994-71-8)

Guidance literature:

170-200°C; 7 h;

Reference yield: 59.0%

sodium acetylide (1066-26-8) + tributyltin hydroxide (1067-97-6) → bis(tributylstannyl)acetylene (994-71-8)

Guidance literature:

In diethyl ether; reflux for 10-12 h;

Reference yield: 35.0%

tributyltin chloride (1461-22-9) + acetylene (74-86-2,25067-58-7) → tributylethynyltin (994-89-8) + bis(tributylstannyl)acetylene (994-71-8)

Guidance literature:

With n-butyllithium; In hexane; (N2); introducing an C2H2 stream into a soln. of n-BuLi at -20 to -30°C with stirring; after 10 min warming to room temp.; cooling to 0°C; dropwise addn. of (C4H9)3SnCl soln. with stirring; refluxing for 2 h; filtration; fractinated distn. affords (C4H9)3SnC2H; residue proves to be ((C4H9)3Sn)2C2; (119)Sn-NMR, refractive index;
