The direct polymerization method comprises the direct polymerization of aromatic diamine with the aromatic tricarboxylic acid anhydride in the presence of a dehydration catalyst. Dehydration catalysts include triphenyl phosphite, triphenyl phosphate, and tri-n-butyl phosphite. The reaction... 

Use.1 The reagent has been used in the same way as dimethylcopperlithium for conjugate addition to a,/3-unsaturated ketones however, with the present reagent various salts (lithium iodide, lithium bromide, etc.) must be present. The tri-/i-butyl phosphite and tri-n-butyl phosphine complexes have been prepared but are less useful.

The large solubility (xhq = 2.35 at 10 C) of HCl in tri-n-butyl phosphate is in accord with its description as a strongly basic solvent [Tuck and Diamond (1958) ]. Trialkyl phosphites of ordinary reactivity, e.g., (n-BuO)3P, quickly react at room temperature with HCl to give the dialkyl hydrogen phosphite and alkyl chloride. This reaction does not occur with triphenyl phosphite (xhci = 0.69 at 10°C) and has a low probability of occurrence for tris(trichloroethyl) phosphite (xna = 0.46) at 10 C. The Xhci value for phenol is 0.09 and that for CI3CCH2OH is 0.087 at 10°C it therefore appears that the lone pair of electrons on phosphorus in these phosphites have electron-donor function, and indeed the postulated mechanism for the quick reaction between the n-butyl phosphite and hydrogen chloride is based on this effect. The Xhci value for dialkyl hydrogen phosphites of ordinary reactivity is about 2 at 10°C.
