| titleOfInvention | A METHOD FOR PREPARING ORGAN-PHOSPHORUS COMPOUNDS |
| abstract | Improvements introduced in the object of the main patent or in a method for the preparation of an organo-phosphorus compound having the formula: ** (See formula) ** where R3 and R4 are the same or different and each is an alkoxy group having 1 to 4 carbon atoms, and each group is substituted with a halogen atom; X is an oxygen or sulfur atom; Y3 and Y4 are the same or different and each is an alkoxycarbonyl group or an alkoxycarbonylalkoyl group; or Y3 is a hydrogen atom or a methyl group when Y4 is an alkoxycarbonyl group or an alkoxycarbonylalkoyl group; or Y 4 is a hydrogen atom or a methyl group when Y 3 is an alkoxycarbonyl group or an alkoxycarbonylalkoyl group; said "alkoxycarbonyl" and "alkoxycarbonyl" groups having said "alkoxycarbonylalkohyl" groups, each having from 3 to 6 carbon atoms, and having the "alkyl" of said "alkoxycarbonylalkoyl" groups from 1 to 4. carbon atoms, characterized in that said method comprises the reaction of a phosphorus compound of the formula with a coumarin compound of the formula ** (See formula) ** where Z is a halogen atom when M is a hydrogen atom or an alkali metal atom, or Z and M are each a hydrogen atom.
