-
The reaction of 2,6-di-tert-butylphenyl phosphorodichloridite or its para-substituted derivatives with 1 equiv of water in the presence of 2 equiv of trialkylamine forms a family of novel P(III)-O heterocycles, the 1,3,5,2,4,6-trioxatriphosphorinanes.Thes

- STUDIES OF THE 1,3,5,2,4,6-TRIOXATRIPHOSPHORINANE RING SYSTEM
-
Phosphorodichloridites with sterically demanding O-aryl groups are known to undergo controlled partial hydrolysis to give 1,3,5,2,4,6-trioxatriphosphorinane derivatives, but the O-(1-adamantyl) and O-neopentyl groups failed to provide control of the hydro

-
An improved process for preparing 2,4,6-tris(substituted phenoxy)-1,3,5,2,4,6-trioxatriphosphorinanes is realized when the appropriate substituted-phenylphosphorodichloridite is reacted with water in the presence of a trialkyl amine wherein the alkyl groups contain 4 to 8 carbon atoms in acetone as the sole solvent, to provide the desired 2,4,6-tris(substituted phenoxy)-1,3,5,2,4,6-trioxatriphosphorinanes in increased yields and of a higher purity.

- 2,4,6-Tris(substituted phenoxy)-1,3,5,2,4,6-trioxatriphosphorinanes as stabilizers
-
Novel stabilizers for organic materials subject to degradation, 2,4,6-tris(substituted phenoxy)-1,3,5,2,4,6-trioxatriphosphorinanes are prepared by the reaction of substituted-phenylphosphorodichloridites, water and amines. The 2,4,6-tris(substituted phenoxy)-1,3,5,2,4,6-trioxatriphosphorinanes, form effective stabilizer combinations with hindered and partly hindered phenols such as hydroxyphenylalkyleneyl isocyanurates, particularly when used in polymers, polyolefins, for example.
