Abstract

Modification of substrates by trialkoxysilane reagents is the most common method employed for surface functionalization. Classically, the mechanism for surface reactivity in trialkoxysilanes is described as proceeding through a trisilanol intermediate. Here, we present data that contradict this mechanism and propose an alternative mechanism, in which trialkoxysilanes react directly with surface hydroxyl groupsvia an addition-elimination type mechanism.
