Technology Process of Dibutyldipentyltin

There total 6 articles about Dibutyldipentyltin 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: 42.0%

amyl iodide (628-17-1) + dibutyltin chloride (683-18-1) → dibutyldipentyltin (78693-52-4)

Guidance literature:

With zinc; In tetrahydrofuran; water; under air atm., at room temp., cosolvent media: H2O(NH4Cl)/THF/Zn, alkyliodide was added dropwise to the alkyl tin halide in solvent mixt. over 15 min, reaction time: 3.5 h; Zn was filtered off, aq. phase was extd. three times with n-pentane, organic phase was washed with sat. aq. NaCl and dried over MgSO4, solvent was removed, crude oil was distilled under vac., then chromd. using n-hexane; (119Sn NMR monitoring);

DOI:10.1016/S0022-328X(00)00388-0

Reference yield:

tetra-n-butyltin(IV) (1461-25-2) + tetrapentyltin (3765-65-9) → pentyltributyltin (78693-51-3) + dibutyldipentyltin (78693-52-4) + butyltripentyltin (78693-53-5)
