(SNAr) for the synthesis of liquid-phasecombinatoriallibraries was studied. The real and “virtual” combinatoriallibraries of diaryl ethers were synthesized by the reactions of pentafluoropyridine with phenol and its derivatives. Some criteria for the estimation of the quality of the libraries were formulated. A rational methodology for the preparation of representative combinatorial mixtures on the
Alkaline metal fluorides in graphite - new catalysts in organic synthesis. I. Reactions of polyfluoroaromatic compounds with O- and N-nucleophilic agents
The paper reports the use of new catalysts - alkaline metal fluorides in graphite of the general formula C8MF, where M=Li, Na, K, Rb or Cs, in the reactions of polyfluoroaromatic compounds with aromatic OH-acids and piperidine. These compounds are shown to have a high activity in the above processes, exceeding that of similar free fluorides of alkaline metals.
