Silanol, 1,1,1-triethyl-, 1-acetate → Hexaethyldisiloxane

Participants

Reaction Steps

To the resulting solution of mesylate (4) is added 4-mercaptopyridine (129 mg; 1.4 equivalents) and acetonitrile (2 ml) and stirred under ice cooling for 1 hour. The reaction mixture is poured into ice-water and adjusted at pH 6.0. The organic layer is separated, washed with aqueous sodium hydrogen carbonate and water, dried, and concentrated in vacuum to give pyridyl sulfide (7) as foamy residue.
