| 摘要 |
There are disclosed novel phosphorous-containing compounds including and derived from hydrogen phosphonates. The compounds of the present invention can be prepared by reacting a hydrogen phosphonate with: (a) an ethylene derivative in a Michael reaction, (b) an amine or amide and formaldehyde in a Mannich reaction, (c) an aldehyde or ketone, (d) a halogen, (e) carbon tetrachloride and an alkylamine, and (f) carbon tetrachloride and a hydroxyphosphate. Halophosphonates produced according to procedure (d) can also be used in reactions with (a) alkylamines and (b) hydroxyphosphonates or epoxides to produce the compounds of the present invention.
