There total 4 articles about 4-Oxa-2-thia-3-phospha-1-stibapentane, 3-methoxy-1,1-diphenyl-, 3-sulfide 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: 96.0%

sodium O,O-dimethyl phosphorodithioate (26377-29-7) + diphenylantimony(III) chloride (2629-47-2) → diphenylantimony(III) O,O-(CH3)2-dithiophosphate (126443-49-0)

Guidance literature:

In benzene; byproducts: NaCl; addn. of Na-salt in benzene to Ph2SbCl, refluxing for 2 h; filtn. of NaCl, removing of the volatile fraction under vac. gives a liquid, dissoln. in petroleum ether and keeping in a deep freezer overnight, solvent removal in vac., elem. anal.;

Reference yield: 51.0%

diphenylantimony(III) acetate (5613-52-5) + O,O-dimethyl phosphorodithioic acid (756-80-9) → diphenylantimony(III) O,O-(CH3)2-dithiophosphate (126443-49-0)

Guidance literature:

In benzene; byproducts: CH3CO2H; addn. of (CH3O)2PS2H (5.5 mmol) to a soln. of (C6H5)2SbO2CCH3 (5 mmol) in anhydrous benzene; stirring under reflux for 2 h; filtration;; removing the solvent under vac.; dissolving the obtained oil in acetonitrile; crystallization on cooling; elem. anal.;;
