## Abstract For mass spectrometric studies 1‐phenyl‐2‐phenyl‐1‐^13^C‐ethene‐1‐^13^C (trans‐stilbene) was synthesized from acetic‐1‐^13^C acid and acetic‐2‐^13^C acid via methylcyclohexene‐1‐^13^C and ‐α‐^13^C and toluene‐1‐^13^C and ‐α‐^13^C. No scrambling of the label was observed during the aroma

Abstract
In an effort to prepare an improved carbon‐rich target material for the accelerator production of ^13^N labelled ammonia for use in positron emission tomography (PET), sulfonated poly(styrene/divinylbenzene) has been evaluated. The preparation of this target material using naturally abundant carbon‐12 compounds was investigated in an effort to optimize conditions for the preparation of the analogous carbon‐13 target material which may provide a cost‐effective method for producing nitrogen‐13 labelled ammonia via proton irradiation. As part of this study, phenyl‐13C6‐ethene was synthesized in three steps starting from benzene‐13C6. Copyright © 2001 John Wiley & Sons, Ltd.
