摘要：
A novel process for preparing in a high purity and in a high yield phosphorus compounds having a phosphate-phosphonate bond within one molecule, along with only a small amount of a by-product, without being restricted by the kind of a phosphonate having an alcoholic hydroxyl group which is a raw material, without using a catalyst such as magnesium chloride, but only using a nitrogen-containing basic compound.
