2-Mercaptoethanol → 2-[Methyl-bis(2-sulfanylethoxy) silyl]oxyethanethiol

Participants

Reaction Steps

The 2-[methyl-bis(2-sulfanylethoxy) silyl]oxyethanethiol (2) was synthesized according to the same procedure as 2-[dimethyl(2-sulfanylethoxy)silyl]oxyethanethiol (1), using triethylamine (8.08 g, 0.080 mol), trichloromethylsilane (3.98 g, 0.027 mol), and 2-mercaptoethanol (6.24 g, 0.080 mol) in ether (400 mL). 2-[methyl-bis(2-sulfanylethoxy) silyl]oxyethanethiol (2) was obtained as a clear, colorless, foul-smelling liquid (6.81 g, 93.2%). The product was purified by distillation under reduced pressure and obtained as a clear, colorless, foul-smelling liquid (4.53 g, 62.0%), Bp=128-129° C. at 0.25 mmHg.
