Solubilities of (2,5-dihydroxyphenyl)diphenyl phosphine oxide in selected solvents

A phosphorus-containing flame retardant (2,5-dihydroxyphenyl)diphenyl phosphine oxide (HPO) was characterized by a differential scanning calorimeter (DSC), thermogravimetric analysis (TGA), elemental analysis, and nuclear magnetic resonance (1H NMR and 31P NMR). Using a static analytical method, the solubilities of HPO were measured in 12 solvents and correlated with an empirical equation. The estimated uncertainty of all of the solubility values on error analysis and repeated observations was within 2.0 %.

A new synthetic approach to aromatic diols substituted with two, three, and four (similar or different) phosphorus groups via the Michael-type addition of the P-H bond containing reagents to p-benzoquinone derivatives, reoxidation, and subsequent addition

Selective Ortho Lithiation of (2,5-Dimethoxyphenyl)diphenylphosphine Oxide and Trapping of the Resulting Aryllithium with Electrophiles

The title compound undergoes predominant 6-lithiation, ortho to the methoxy and phosphinoyl groups, on reaction with t-BuLi in THF under conditions of thermodynamic control at low temperature.The organolithium compound is stable at least to 0 deg C and can be trapped by a range of electrophiles to give the corresponding tetrasubstituted (diphenylphosphinoyl)arenes in moderate to good yield.The iodide formed by this sequence undergoes Ullman coupling to the diphenyl, which exhibits a novel restricted rotation phenomenon, in good yield under mild conditions. (2,5-Dimethoxyphenyl)diphenylphosphine sulfide lithiates exclusively at the 4-position under the same conditions, whilst the corresponding phosphine is unreactive.
