Reactions Involving Poly functional Reagents

Triarylphosphine oxides were prepared from ArP(0)Cl2 and arylmag-nesium bromide and the resulting species were involved in polycondensation in two ways either after cleavage of the methoxy group to a hydroxy function, or by reaction with a dihydroxy reagent (e.g., bisphenol A). The resulting poly(arylene ether phosphine oxide) type plastics are of interest as...
