Abstract
3-Chloropropylalkyldiethoxysilanes (alkyl: butyl, hexyl and benzyl) were synthesized by the Grignard reaction of 3-chloropropyltriethoxysilane; The amination of the formed 3-chloropropylalkyldiethoxysilanes with ethylenediamine produce 3-(2-amino-ethyl)aminopropylalkyldiethoxysilanes (alkyl: butyl, hexyl).
