โœฆ Synopsis

Abstract

A range of organic compounds have been tritiated (and in some cases deuteriated) via hydrogen isotope exchange reactions using polymer supported base catalysts. The problem of poor thermal stability of some commercially available anion exchange resins, which limits their use as tritiation catalysts, has been overcome by the preparation of a more stable polymer supported pyridinium salt. The anion exchange resins are as effective at very high activities of tritiated water as they are at low and compounds containing nitro groups, which poison metalโ€catalysed exchange reactions, can be successfully labelled.
