Please see attached file were they protect selectively 1-thioglycerol. (see prep 5a)

Hope it helps

What about making a thiosilyl ether?

You should consult Greene's protecting group book if you have access to it.

I think you can oxidation of the thiol to form disulfide with iodine or H2O2. This can be forming the dimer or with another thiol (but this type of compounds are really pungent...). Reduction with NaBH4 will give back the thiol, 

As the thiol is more nucleophilic, Cbz or Fmoc will work as well THF/H2O NaHCO3. 

I think you can form thio ethers selectively but the cleavage requires Na/NH3, Hg(i) or Ag(I) these may not be readily available.

Hope it helps

thanks alot

You can protect thiol group in ether synthesis converting it into Na salt on treatment with alkali KOH or NaOH & then react with alkyl halide to get ether just like Williamson's synthesis.
