Usage

General Description

2-(diphenylphosphoryl)ethanol is an organic compound with the chemical formula C14H15O2P. It is a phosphoric acid ester that is used as a flame retardant and plasticizer in various industrial applications. This chemical is a colorless to pale yellow liquid with a mild, sweet odor. It is insoluble in water but soluble in organic solvents. Studies have shown that it has low acute toxicity, but prolonged exposure may cause irritation to the skin, eyes, and respiratory system. 2-(diphenylphosphoryl)ethanol is used in the production of polymers, resins, and other materials to improve their fire resistance and flexibility.

2-Phenoxyethyldiphenylphosphine oxide as an equivalent of diphenylvinylphosphine oxide in nucleophilic additions

A facile method for the synthesis of β-functionalized ethyldiphenylphosphine oxides is developed based on readily available 2-phenoxyethyldiphenylphosphine oxide used as an equivalent of diphenylvinylphosphine oxide in the reactions of addition of different PH- and NH-nucleophiles in DMSO in the presence of KOH. The transformations of labile phosphine oxides of a general formula Ph2P(O)CH2CH2OR, where R = Ph, H, or Ph2P(O)CH = CH2, in aq.KOH/DMSO and solid KOH/DMSO systems are explored in the absence of nucleophilic reagents.

Ruthenium-catalyzed regio- and enantioselective allylic substitution with water: Direct synthesis of chiral allylic alcohols

Less is more: A new route to access chiral allylic alcohols through the regio- and enantioselective substitution of monosubstituted allylic chlorides with water has been developed. The reaction is catalyzed effectively by planar-chiral cyclopentadienyl ruthenium complexes (see scheme). Copyright
