Patent ID: 7084080

Claim:
A method of synthesizing an aminosilane source reagent composition, comprising: (a) reacting an aminosilane precursor compound with an amine source reagent compound, wherein the amine source reagent compound is selected from the group consisting of: B(NR 1 R 2 ) and wherein B is selected from the group consisting of H, Li, Na, K, Zn and MgBr; N is nitrogen; R 1 and R 2 are same or different and each is independently selected from the group consisting of H, aryl, perfluoroaryl, C 1 –C 8 alkyl, and C 1 –C 8 perfluoroalkyl; and n is from 1–6, in a solvent system comprising at least one non-polar solvent, at temperature in a range from about −30° C. to about room temperature, for a period of time sufficient to produce a reaction mixture comprising partially substituted aminosilane components, unreacted aminosilane precursors and unreacted amine components; (b) combining the reaction mixture with at least one polar activating solvent component to at least partially solvate and activate the unreacted amine components, wherein the polar activating solvent comprises a Lewis base selected from the group consisting of ethers and tertiary amines; and (c) continuing the reaction of step (b) at temperature in a range from about 0° C. to about 100° C. for a period of time sufficient to produce the aminosilane source reagent composition, wherein the aminosilane source reagent composition comprises less than 1000 ppm halogen.
