Technology Process of (R)-(-)-triphenyl-sec-butyltin

There total 5 articles about (R)-(-)-triphenyl-sec-butyltin 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:

sec-butyl methanesulfonate (16156-54-0) + sodium triphenylstannide → (R)-(-)-triphenyl-sec-butyltin (33766-66-4,81928-51-0,33766-65-3) + hexaphenylditin (1064-10-4)

Guidance literature:

In tetrahydrofuran; Mixt. was stirred at room temp. over night;; H2O and ether was added to a soln., layers were sepd.; organic layer was washed with 20% KF and brine, then dried over K2CO3, mixt. was dissolved in hot EtOH, filtered, crystd. by cooling, ppt. was chromd. on silica column (pentane); elem. anal.;;
