Reaktionsschritte
A mixture of 3-mercaptopropyltrimethoxysilane (19.6 g, 0.1 mol), 2-isopropenyloxazoline (11.1 g, 0.1 mol) and 20 drops of triethylamine was heated under a nitrogen atmosphere at 80° C. overnight. A 3.2 g sample of the resulting mixture was vacuum fractionated (150° C., 0.06 torr) using a Kugelrohr apparatus to give 2.43 g of a clear, colorless distillate of a silane coupling agent (6-(2-oxazolinyl)-4-thiaheptyltrimethoxysilane) having the formula (CH3O)3SiCH2CH2CH2SCH2C (Me) C3 H4NO, where --C3H4NO represents an oxazolinyl group.
