Abstract: A multifunctional organosilicon compound is provided which has the general formula XSi([OSiR2]p-0-SiR2Y)a(R1)3-a— ln the formula, X is selected from H and ethylenically un saturated moieties; each Y independently comprises a functional moiety selected from alkoxysilyl moieties, acryloxy moieties, and epoxide moieties; each R is an independently selected hydrocarbyl group; each R1 is an independently selected hydrocarbyl group; subscript a is 1, 2, or 3; and each subscript b is independently 0, 1, or 2. A method of preparing the multifunctional organosilicon compound is also provided. The method comprises reacting (A) an organosilanol compound and (B) a silane compound having at least two hydrolysable groups. A functionalized siloxane compound prepared from the multifunctional organosilicon compound, a method of preparing the functionalized siloxane compound, and an adhesive comprising the functionalized siloxane compound are also provided.
