Participants

Reaction Steps

The procedure and apparatus of Example 1 were used with 22.4 g (0.207 m) of propane-1,3-dithiol, 46.4 g (0.207 m) of (3,3-dimethoxypropyl)trimethoxysilane, 0.14 g of p-toluenesulfonic acid, and 100 ml of xylenes solvent. Methanol was removed by distillation as the contents of the flask were heated at reflux (143°) for 2 hours. The crude product, excluding solvent, contained 75% of the title product and 7.4% of the monosubstituted product, (MeO)3Si(CH2)2CH(OMe)S(CH2)3SH, as determined by GC/MS.
