Abstract
A method of preparing a multifunctional organosilicon compound is provided. The method comprises reacting (A) an organosilanol compound comprising a functional moiety selected from alkoxysilyl moieties and acryloxy moieties and (B) a hydridosilane compound having at least two hydrolysable groups in the presence of (C) an acetate salt. A multifunctional organosilicon compound prepared according to the method is also provided.

A method of preparing a multifunctional organosilicon compound, said method comprising:
- reacting (A) an organosilanol compound comprising a functional moiety selected from alkoxysilyl moieties and acryloxy moieties and (B) a hydridosilane compound having at least two hydrolysable groups in the presence of (C) an acetate salt comprising a complex having the general formula [R6C(O)O]−[M]+, where R6 is a substituted or unsubstituted methyl group and M is an alkali metal, thereby preparing the multifunctional organosilicon compound,
- wherein, the organosilanol compound (A) has the following general formula:
- where Y is the functional moiety selected from alkoxysilyl moieties and acryloxy moieties,
- each R is an independently selected hydrocarbyl group, and subscript a is 0, 1, or 2.
