1-Propanethiol, 3-(triethoxysilyl)- → Phthalimide

Participants

Reaction Steps

A 1-quart (0.946 l) glass reactor was charged with 400 ml of chloroform, 55.4 g (0.21 mole) of N-cyclohexylthiophthalimide, and 47.6 g (0.20 mole) of 3-mercaptopropyltriethoxysilane dissolved in 400 ml of chloroform. The reaction was stirred and allowed to stand overnight to give white needles of phthalimide (35.2 g) which were separated by filtration and identified by mass spectrometry analysis. The solvent was distilled from the filtrate to give 56.9 g of an oil identified as cyclohexyl-3-dithiopropyltriethoxysilane by mass spectrometry analysis. This oil (53 g) was dissolved in 100 ml of acetone and homogeneously dispersed into N330 carbon black, with the acetone being stripped away.
