A method for providing .sup.11C-labeled cyanides from .sup.11C labeled oxides in a target gas stream retrieved from an irradiated high pressure gaseous target containing O.sub.2, wherein .sup.11C labeled oxides are reduced with H.sub.2 in the presence of a nickel catalyst under a pressure and a temperature sufficient to form a product stream comprising at least about 95% .sup.11CH.sub.4, the .sup.11CH.sub.4 is then combined with an excess of NH.sub.3 in a carrier/reaction stream flowing at an accelerated velocity and the combined .sup.11CH4 carrier/reaction stream is then contacted with a platinum (Pt) catalyst particulate supported on a substantially-chemically-nonreactive heat-stable support at a temperature of at least about C., whereby a product stream comprising at least about 60% H.sup.11CN is provided in less than 10 minutes from retrieval of the .sup.11C labeled oxide.
