General Description

Diphenylphosphinic acid (DPPA, hdpp) is an organophosphinic acid compound. It finds application as a reactive flame-retardant and promoter for palladium catalytic systems. Thermal degradation of DPPA has been studied by thermogravimetric analysis (TGA) method. DPPA reacts with cadmium nitrate in dimethylformamide solvent to afford the one-dimensional coordination polymer catena-poly[[bis(dimethylformamide-κO)cadmium(II)]-bis(μ-diphenylphosphinato-κ(2)O:O′)]. It has been repoted to promote the carbonylation of nitrobenzene and aniline to diphenylurea. Ortho-lithiated DPPA can form mono ortho-functionalized derivatives by electrophilic trapping and biphenyl-2,2′-diylbis(phenylphosphinic acid) by copper catalyzed coupling.

Purification Methods

Recrystallise it from 95% EtOH and dry it under vacuum at room temperature. [see Kosolapoff Organophosphorus Compounds J Wiley, NY, 1950, Kosolapoff and Maier Organic Phosphorus Compounds Wiley-Interscience, NY, 1972-1976, Beilstein 16 IV 1036.]
