PHOSPHORUS-CONTAINING COMPOUND AND CURING EPOXY RESIN COMPOSITION CONTAINING SAME

Provided is a novel phosphorus-containing compound represented by general formula (I). The compound has reactivity with a glycidyl group and is therefore capable of providing a curing epoxy resin composition that is expected to achieve flame retardation and reduction of dielectric constant. wherein m is a number of 1 to 10; R1, R2, R3, and R4 are each hydrogen, alkyl, or aryl; R5 is alkyl, alkanediyl, alkanetriyl, alkanetetrayl, or an aromatic group; X is oxygen or sulfur; Y is oxygen, sulfur, or ═NR′; and R′ is hydrogen, alkyl, or aryl.

Synthesis of Phenyl Phosphorodiamidates

Two procedures are described for the synthesis of phenyl phosphorodiamidates in high yields.These compounds can be represented by the general formula 6 and are used for cyclisation reactions leading to phosphabarbituric acids.
