Technology Process of Dimethyltin

There total 6 articles about Dimethyltin 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:

trimethyl(trifluorsilyl)stannane (126087-12-5) → methyltrifluorosilane (373-74-0) + dimethylstannylene (23120-99-2)

Guidance literature:

N2 atmosphere, high vac. line; heating (330°C, 40 min); IR-monitoring;

Reference yield:

trimethyltin(IV)chloride (1066-45-1) + trimethyl(trimethylstannyl)silane (16393-88-7) → hexamethyldistannane (661-69-8) + tetramethylstannane (594-27-4) + dimethylstannylene (23120-99-2)

Guidance literature:

With chloro-trimethyl-silane; In methanol; byproducts: Me3SiOMe; a mixt. of 0.118 M Me3SiSnMe3, 0.022 M Me3SiCl, and 0.276 M Me3SnCl in methanol was kept for 7 h, reaction was followed by (1)H NMR spectroscopy; at no stage Me6Sn2 was formed, rate consts. are given; not isolated, identified by (1)H NMR spectrum, polymer was isolated from a separate expt. and identified by mass spectrum (repeated Me2Sn unitswith one Si and perhaps one Cl only as end groups); Kinetics;
