The present invention provides a method of making sulfur containing fluoroalkyl amines which overcomes the problems previously known methods. Unlike previously known methods, the method of the present invention can achieve higher yields of sulfur containing fluoroalkyl amines without resorting to costly solvents. Furthermore, unlike previously known methods, the method of the present invention can produce oxidized forms of sulfur containing fluoroalkyl amines wherein the sulfur atom thereof is oxidized.
The present invention is directed to a fluorosilane represented by (L)
