• Cyclisations via fluoride ion induced isomerisations: a route to some novel perfluoroheterocyclic compounds
  作者：Paul H. Ogden

  DOI：10.1039/j39710002920

  日期：——

  In the presence of caesium fluoride tetrafluoroformaldehyde azine reacts with difunctional perfluoroacyl fluorides of the structure [CF2]n(COF)2 to produce perfluoroheterocyclic compounds of the general structure CF3[graphic omitted] (n= 2 to 4). A heterocycle is also produced with oxalyl fluoride, but with carbonyl fluoride the major product is a substituted hydrazine.
