There total 2 articles about Pentaammine(trifluoromethanesulfonato)osmium(III) triflate 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: 100.0%

{Os(NH3)5Cl}Cl2 + trifluorormethanesulfonic acid (1493-13-6) → pentaamminetrifluoromethanesulfonato osmium(III) trifluoromethanesulfonate (83781-30-0)

Guidance literature:

In not given; distd. CF3SO3H is added to (Os(NH3)5Cl)Cl2, stirred mixt. is heated to 120°C, flow of N2 is maintained, after 1 h flask is stoppered, heating continued for 10-15 h at 120°C, soln. cooled to room temp. under stream of N2; soln. is cooled to 5°C, anhyd. diethyl ether is added dropwise to stirred soln., filtn., white powder is washed;

Reference yield: 96.0%

osmium(II) pentaammine dinitrogen dichloride + trifluorormethanesulfonic acid (1493-13-6) → pentaamminetrifluoromethanesulfonato osmium(III) trifluoromethanesulfonate (83781-30-0)

Guidance literature:

With bromine; byproducts: N2, HBr; anhyd. CF3SO3H is added to (Os(NH3)5(N2))Cl2, liq.Br2 is added, const. flow of N2 or Ar commenced to stir soln., temp. maintained at 50-60°C, when N2 evolution ceased, soln. heated to 110°C, after no Br2 remains, soln. cooled to room temp.; soln. is cooled to 5°C, anhyd. diethyl ether added dropwise, cream ppt. is formed, collected, air-dried, solid washed (anhyd. diethyl ether) until washings colorless, dried, purified by boiling suspn. in chloroform; elem. anal.;
