WebIn the second step, bis (3-aminophenyl)phenyl phosphine oxide (m-DAPPO) was prepared by the reduction of m-DNPPO by stannous chloride method . This method was used for the synthesis of this diamine, since the reduction with hydrogen over Pd/C in the hydrogenation shaker produced a low yield of 28% [ 96 ]. Phosphine oxides are phosphorus compounds with the formula OPX3. When X = alkyl or aryl, these are organophosphine oxides. Triphenylphosphine oxide is an example. An inorganic phosphine oxide is phosphoryl chloride (POCl3).
