New isotopically marked oxalyl fluoride compounds useful for production of tracer materials in organic chemistry, polymer chemistry and medicine
Isotopically marked oxalyl fluoride compounds (I) are new. Isotopically marked oxalyl fluoride compounds of formula F-(jCkO)-(mCnO)-F (I), are new. j, m = 11 - 14; k, n = 15-18; and provided that the combination k, m = 12 and n = 16 is excluded. An Independent claim is also included for the production of (I) by fluorination of correspondingly marked or unmarked carbon monoxide with a dioxygenyl salt (II) having a fluorinated anion at -120 - 120 deg C.
