摘要:
                                Bisphenol A reacted as its disodium salt with tetrafluoroethylene and carbon dioxide followed by dimethyl sulfate to give in high yield a symmetrical dimethyl ester assembled from seven structural elements.  This diester was transformed into the corresponding diol, diamide, diamine, diisocyanate, and bis(methyl carbamate).  Analogous diesters were prepared by using bisphenol A and chlorotrifluoroethylene as well as hexafluorobisphenol A and tetrafluoroethylene.  Both of these esters were transformed into other bifunctional derivatives.  Catalytic hydrogenation of the diol derived from bisphenol A and tetrafluoroethylene was accompanied by hydrogenolysis of the aryl-oxygen bonds.
