- 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.

- ALKALINE SOLVOLYSIS OF DIAMIDOPHOSPHATES
-
Mechanism of alkaline solvolysis of phenyl diamidophosphates is discussed on the basis of its selectivity, activation entropy and steric effects.All methods used show that the reaction proceeds by SN2 mechanism via an intermediate, containing a pentavalent phosphorus.

- 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.

- SYNTHESE DE TRIOXO-2,4,5-DIAZA-1,3-PHOSPHOLIDINES-2-TRISUBSTITUTEES ET REACTIONS AVEC LES ALCOOLS ET LES AMINES
-
The 2,4,5-trioxo-1,3-diaza-2-phospholidene trisubstituted, 3, are synthetized in the absence of any base, by the reaction of oxalyle chloride on the primary phosphordiamides 1.The 3 cycles are opened with a Formel bond cleavage in the presence of alcohols and a Formel one in the presence of amines.It can be assumed from the results that Formel pentacoordinate X complex is formed, whose breakdown in the case of amines is slower than the attack on one or the other of the carbonyles.
