Tetrahydrothiophene → HCID 86654382, compound

Participants

Reaction Steps

2.0 g of tetrahydrothiophene and 18 g of ethyl acetate were charged into a 100 mL flask to be dissolved. While stirring the resultant mixed solution with a magnetic stirrer, to the mixed solution, a solution in which 9.9 g of trimethoxysilylpropyl iodide was dissolved in 24 g of ethyl acetate was gradually added at room temperature in a nitrogen atmosphere. The reaction mixture was refluxed over 3 days and therefrom, ethyl acetate was distilled off under reduced pressure. The resultant concentrate was dropped into 100 mL of diethyl ether and therefrom, tetrahydrothiophene and trimethoxysilylpropyl iodide as by-products were removed. This purification was repeated three times and then remaining diethyl ether was distilled off under reduced pressure, followed by dissolving the resultant concentrate in methanol to obtain a 30% methanol solution of trimethoxysilylpropyltetrahydrothiophene iodide.
