Technology Process of Dimethyl selenoxide

There total 1 articles about Dimethyl selenoxide 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: 10.0%

dimethyl selenide dichloride (1178904-71-6) → dimethylselenide (593-79-3) + dimethyl selenoxide (4371-90-8)

Guidance literature:

With sodium hydrogencarbonate; dimethyl sulfoxide;

DOI:10.1246/cl.1983.33

Reference yield: 84.0%

1-phenyl-1-thio-4-methyl-4-chloro-1λ5,4-phosphastanninane (150592-85-1) + dimethyl selenoxide (4371-90-8) → 1-phenyl-1-oxo-4-methyl-4-chloro-1λ5,4-phosphastanninane

Guidance literature:

In chloroform; byproducts: (CH3)2Se; Me2SeO in CHCl3 was added to a soln. of the Sn-compd. in CHCl3, refluxed for 15 min; volatiles were removed in vac., addn. of CHCl3, filtered, washed with water, dried over Na2SO4, recrystd. from CH2Cl2/hexane; elem. anal.;

Reference yield: 33.0%

6,6-Diphenylfulvene (2175-90-8) + dimethyl selenoxide (4371-90-8) → <5-(Diphenylmethylen)-1,3-cyclopentadien-1-yl>dimethylselenonium-perchlorat (119038-40-3)

Guidance literature:
