Aromatic and aliphatic thiols can be protected by reaction with t-BuMe 2SiOCH2Cl in DMF in the presence of a base (2,6-lutidine or proton sponge); the resulting t-BuMe2SiOCH2SR or t-BuMe2SiOCH2SAr are deprotected by sequential treatment with Bu4NF and I2 to give symmetrical disulfides. Another mode of deprotection involves reaction with a sulfenyl chloride; this process gives an unsymmetrical disulfide and was examined with Me(CH2) 11SCH2OSiMe2Bu-t and three sulfenyl chlorides.
