A composition of matter is disclosed that comprises a compound of the formula A<SUB>n</SUB>R, wherein: A is R<SUB>1 </SUB>is hydrocarbyl; m is 0 or 1; n is 1, 2, or 3; R is selected from the group consisting of: mono-, di-, and trivalent aliphatic groups; mono-, di-, and trivalent aromatic groups; five- and six-membered heterocyclic rings comprising n carbon atoms bonded to A, at least one nitrogen atom, and, optionally, at least one sulfur atom; and wherein R<SUB>2 </SUB>and R<SUB>3 </SUB>are independently selected from the group consisting of hydrogen and hydrocarbyl. These compounds are useful as coupling agents in filled elastomer compositions.
