2. outline 1.Background 2.Results and discussion 3.The future plan 2

3. Background Organophosphorus compounds pesticide flame retardant medicine At present there are more than 100 kinds of organophosphor us pesticide in the world. Phosphorus flame retardant sales account for more than half of the total sales of flame retardants antibacterial agents enzyme inhibitors anti HIV agents 3

4. Background : Synthesis β-Aminophosphonates No free radical reaction 4
