Descrição geral
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.
Aplicação
Diphenylphosphinic acid is an important starting material for the synthesis of organophosphinic compounds. Diphenylphosphinic acid may be used for the preparation of coordination polymers, via reaction with alkaline earth metal salts in dimethylformamide (DMF) solvent:
- [Mg3(O2PPh2)6(DMF)2]·2DMF
- [Ca(O2PPh2)2(DMF)2]
- [Sr(O2PPh2)2(DMF)2]
- [Ba(O2PPh2)2(DMF)2]

Reaction of alkaline earth metal salts with diphenylphosphinic acid in dimethylformamide solvent afforded four coordination polymers: [Mg3(O2PPh2)6(DMF)2]·2DMF (I), [Ca(O2PPh2)2(DMF)2] (II), [Sr(O2PPh2)2(DMF)2] (III) and [Ba(O2PPh2)2(DMF)2] (IV) (where DMF is N,N-dimethylformamide). Single-crystal X-ray diffraction revealed that all four compounds produce linear chain
