Applicazioni

For preparing perfluoro-aromatic nitrogen heterocyclic compounds from their perchloro-analogues by exchange with potassium fluoride in the absence of solvent has been extended to the pyridazine system. Tetrafluoropyridazine readily undergoes nucleophilic substitution. Ultrathin plasma polymer films is prepared from tetrafluoropyridazine. The variation in the orientation of products formed with the olefin used in polyfluoroalkylations with tetrafluoropyridazine is discussed.

Note

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents.
